Before the monthly side hurts


  1. There are several reasons why there is pain in the lower abdomen on one side:
  2. Heredity, which is transmitted through the female line. When uterine muscles contract, the nerve endings react very strongly. It is enough to take an anesthetic drug.
  3. Diseases of the female organs. For example, endometritis, ovarian pathology and other factors.
  4. The spiral can cause pain in the lower abdomen. Abortions or other interventions may be provocateurs.
  5. Cystitis, neurological causes or appendicitis should not be ruled out. Diarrhea also causes uterine cramps.
  6. Ectopic pregnancy causes severe pain on one side. With this condition, pain becomes impossible to endure and should be called as soon as possible by a doctor.
  7. Ovulation. A common cause of unpleasant spasms depends on the release of an egg from one ovary. Usually they last no more than a day.
  8. Ovarian apoplexy is the rupture of an organ. Nausea occurs, leading to vomiting and dizziness. The pain is unbearable pricking character.
  9. Hydrosalpinx is a pathology of the fallopian tubes that are filled with serous fluid. This disease is easily identified by a doctor. Most often there are no symptoms, but over time problems may arise with conception.
  10. Endometriosis is characterized by long and abundant critical days.

Physiological pain before menstruation

Mild pain before menstruation is the physiological norm. During ovulation, the egg leaves the cavity of the fallopian tubes, awaiting fertilization. If this does not happen, then the sex cell must be removed from the body along with the uterine mucosa, which increased during the period of ovulation. Because of the separation of endometrial cells, the vessels and nerve endings are damaged, so painful sensations arise.

With primary dysmenorrhea - the pathology of the menstrual cycle, due to which a woman experiences very strong pain and weakness every month - the bleeding may not be very active. In this case, increased discomfort is already a deviation from the norm.

Typically, pain during menstruation begins at 2-3 days, the peak of pain falls on 3-4 days. If during ovulation the egg cell was fertilized, then the menstruation does not occur, the pain does not appear.

Why hurts before the monthly right side

Normal pain before and during menstruation should be only in the lower abdomen and lower back, in other cases it is necessary to think about the causes of discomfort. Some girls complain of moderate or severe pain in the right side, for which there are several reasons.

The reason that the right side is hurting below can be diseases of the genital organs, because the reproductive system is located not only in the lower abdomen, but also higher, approximately to the navel. During menstruation, there is a slight inflammation, so the pain caused by the existing pathologies increases.

Ectopic pregnancy

Pregnancy is the process of carrying a child developing from a fertilized egg. You can learn about its occurrence with the help of a cheap and simple test that reacts to a specific hormone. Often girls are limited to this without undergoing an ultrasound examination. But it is precisely the latter analysis that will help establish whether the fetus has taken the correct position.

The ovum can consolidate not only in the uterus, but also the fallopian tubes or ovaries, then an ectopic pregnancy occurs.

With the pathological development of pregnancy, a woman after 2-3 months begins to experience pain in the right or left side, they have aching, pulling or cutting nature, discomfort is possible in the lower abdomen and back. It arises due to the fact that the fetus begins to stretch the thin fallopian tubes or ovaries.

It is impossible to carry the child during an ectopic pregnancy, because the uterine tube or ovary will be broken, the fetus will die, and the mother’s life will also be at risk. If a pregnant woman has pain in her side, it is necessary to consult a gynecologist and do an ultrasound to exclude the pathological location of the fetus.

Right Ovarian Inflammation

The ovaries are paired organs of the female reproductive system, which are essential for her health and the ability to have a baby. They secrete hormones, eggs, regulate the menstrual cycle, are responsible for the development of secondary sexual characteristics.

The body carefully “monitors” the health of the ovaries, sending blood enriched with oxygen and immune cells, but sometimes it is impossible to avoid diseases of these organs. Various right-sided inflammatory processes can cause the right side to hurt before menstruation.

Oophoritis and adnexitis

Oophoritis and adnexitis are inflammatory processes that affect the ovaries and appendages, and their cause is the addition of a bacterial (staphylococcus, streptococcus, Escherichia coli) or viral infection. Often, pathogens cause inflammation due to prolonged exposure to low temperatures, low immunity, or drastic weight loss.

When oophoritis or adnexitis, side pains are aching or cutting, they intensify before the beginning of menstruation. The inflammatory process in the ovaries is accompanied by increased bleeding during menstruation, fever up to 38-39 degrees, weakness and nausea.

Cyst and polycystic

About a week and a half before the onset of menstruation, when a woman begins to ovulate, there may be constant aching pain in her side, and the cause will be a cyst or polycystic ovary. The cyst is formed due to the fact that the follicle does not fully open inside the ovary, the egg cell does not come out of it, and there the inflammatory process begins with the accumulation of pus or the appearance of compaction. Polycystic - multiple formation of cysts in the ovary.

The cause of the appearance of cysts can be such states:

pathologies of the development of the reproductive system, low or elevated levels of FSH - a hormone that stimulates the formation and release of the egg from the follicles, low or high body weight.

The pains in the cytosis are aching in nature; they occur because hormones begin to influence the ovary so that it releases the egg during ovulation. The discomfort may not be strong, but permanent, therefore unpleasant.


Apoplexy - an emergency condition, accompanied by a violation of the integrity or rupture of the ovary. It occurs because of such reasons:

physical injuries, infection, ectopic pregnancy, varicose veins of the ovary, prolonged inflammation of the ovary and appendages.

When right-sided apoplexy pain in the side will be strong cutting, constant, sometimes because of discomfort, the woman flexes the body and can not bend it. This condition is accompanied by a very high temperature, loss of consciousness, and if a woman is not delivered to the hospital in time, death is possible due to blood loss.


Endometriosis is a pathological increase in the thickness of the uterine mucous membrane. With this disease, menstruation is more abundant, lasts longer (about 9-11 days), pain during menstruation is strong, can give in the right or left side, the ovarian region.

Ill side by endometriosis can dramatically, the sensations will be aching and not brightly expressed. Sometimes pains are accompanied by weakness, a decrease in pressure.

Uterine myoma

Uterine fibroids - a benign neoplasm in the muscle tissue of the uterus, which appears due to hormonal disruptions or the use of local contraceptives, such as spirals. Due to the fact that the tumor begins to "push apart" muscle cells, the nerve endings actively send signals about pain. It can be pulling or cutting, give down the abdomen, in the side or mammary glands.

Stronger than the lower abdomen, chest and right side hurt before menstruation, because then the endometrium of the uterus is compacted, and myoma creates even greater pressure inside the muscle tissue.


An appendix is ​​a small process that is considered a rudiment in humans. It was needed in the early stages of evolution, when animals ate predominantly grass, and this small organ contained good bacteria that helped digest cellulose.

Sometimes the appendix can inflame due to the proliferation of bacteria in it or mechanical damage to the process, in which case an emergency condition develops - appendicitis. The appearance of the inflammatory process may coincide with the onset of menstruation, so the woman risks taking appendicitis for normal menstrual pain.

If a strong cutting pain appeared in the right side, due to which it is impossible to unbend the body, such a state is accompanied by nausea and high temperature, you should immediately go to the hospital, because the rupture of the appendix will be fatal to humans.


The right side also contains the liver and gall bladder, and the inflammation of the latter, cholecystitis, can also be confused with menstrual pains.

Cholecystitis develops due to an excess of bile in the gallbladder or against the formation of stones that do not allow it to go out. Inflammation develops rather slowly, at first it is accompanied by aching pains in the right side, which can be confused with menstrual. Over time, the inflammatory process increases, the temperature rises, the person cannot eat, and the pains are already cutting.

Diverticulitis and increased gas formation

Diverticulitis or inflammation of the intestines, as well as increased gas formation can cause side pain before menstruation. During the premenstrual period, the abdominal cavity, the breasts and legs swell, and fluid accumulates in their tissues. With abdominal swelling in a girl suffering from diverticulitis or flatulence, squeezing of the intestines with accumulated fluid causes worsening of the symptoms of these diseases, stitching or aching pains that can be given to the right side or down of the abdomen.

Intrauterine contraception

Sometimes the question of why pains appear in the right or left side of the body before menstruation is given by women who have an intrauterine device. This device contains hormones, which it gradually releases into the uterus, preventing pregnancy.

After physical injuries, during active sexual intercourse, or if the intrauterine contraceptive device is not properly installed, the helix can budge and travel through the uterus, fallopian tubes, and even the ovaries. This causes a woman to severe pain in the side where the spiral went. At the same time, in addition to discomfort, there is a fever and inflammation in the pelvic area, there is pain during sexual intercourse.

Abortion and diagnostic curettage

During an abortion or diagnostic curettage, the doctor may affect not only the uterine mucosa, but also the underlying smooth muscle tissue. If the wounds are deep, then scar tissue develops in their place, which will be inelastic and susceptible to inflammation; therefore, before menstruation, cutting or aching pains in the lower abdomen may spread to the lower back or side. In this case, the discharge during menstruation will be more abundant than normal.

Medical examination

The first thing that needs to be done for pain in the side is to contact a gynecologist, who will take anamnesis and professional examination. If this doctor can not find the causes of discomfort, then you need to visit a therapist and a surgeon who will palpate the abdominal cavity to find the causes of pain, if they are not associated with diseases of the reproductive system.


Sometimes the usual examination by doctors does not give results, so you need to conduct a more detailed diagnosis. A gynecologist must pass a vaginal smear test, in which pathogenic microorganisms can be detected. They are the cause of inflammation in the ovaries and appendages.

In addition to the smear, it is necessary to do an ultrasound of the pelvic organs and abdominal cavity. The pictures will clearly show many deviations in the state of the organs, for example, inflammation, the appearance of scar tissue, an increase in certain structures, the deposition of stones in the gallbladder.

Treatment of pain in the side before menstruation depends on the cause of this phenomenon. If it is caused by diseases of the reproductive system, it will be necessary to drink a course of antibiotics or antiviral drugs (depending on the nature of the pathogen). When the discomfort provoked an intrauterine contraceptive, it must be urgently removed.

Self-treatment in this case is unacceptable, because the use of heaters for pain relief will only aggravate inflammation and flatulence. Many popular painkillers in this case will not help relieve discomfort.


Since there are a lot of reasons for pain in the side before menstruation, it is difficult to describe all preventive measures, so the main ones will be:

regular visits to the gynecologist (once every 6 months), annual examination by a surgeon, a general practitioner, a neurologist, support for normal microflora in the intestines to avoid flatulence and diverticulitis, avoidance of abdominal injuries, install the IUD only in a good hospital.

Pain in the side before or during menstruation is not the physiological norm, so they can not be ignored or try to cope with them independently. You must visit a gynecologist, a surgeon and a general practitioner to find the cause of this abnormality and get the right treatment.

Pain before menstruation, or during them - the most basic reason for referring women to a gynecologist. However, according to statistics, in the overwhelming number of cases (about 80-90%) it hurts in the right or left side, or in the lower abdomen. Pain arising in the lower back, perineum, thighs occurs much less frequently. But it should be remembered that pain can also occur in connection with surgical or neurological pathology, so when faced with this problem, try to visit a doctor as soon as possible.

Why can pain occur?

All causes of pain in women, the causes can be divided into functional (not related to damage and changes in the structure of organs) and organic (there are lesions of organs, confirmed by modern methods of research).

blood stasis in the uterus during menstruation (bend of the uterus, lack of defloration), ovulatory pain several weeks before menstruation, various violations of the cycle - DMK (dysfunctional uterine bleeding) and primary dysmenorrhea amid hormonal disruptions. inflammatory gynecological diseases (endometritis, adnexitis), benign gynecological diseases (myomas, polyps, endometriosis and adenomyosis), emergency surgical pathology (ovarian apoplexy, torsion of the cyst), intrauterine contraception, non-gynecological diseases (inflammation of the gland, inflammation of the cyst, intrauterine contraception, non-gynecological diseases (inflammation of the gland, inflammation of the cyst), intrauterine contraception, non-gynecological diseases (inflammation of the gland, inflammation of the cysts), intrauterine contraception, non-gynecological diseases (inflammation of the gland, inflammation of the cyst) pregnancy, placental abruption), pain after gynecological operations (abortion, diagnostic curettage).

Inflammatory gynecological diseases

As a rule, inflammatory diseases in the female part have an acute onset, with the onset of hyperthermia, symptoms of general intoxication (weakness, lethargy, loss of appetite) and discomfort in the lower abdomen.

The main feature of adnexitis or salpingitis is frequent unilateral inflammation, therefore only the left or right side hurts. When palpating the appendages through the vagina, enlarged and severely painful formations are felt.

Endometritis is usually accompanied by unusual and foul-smelling vaginal discharge, fever and intoxication, and pain syndrome is concentrated in the lower abdomen. When palpating, the uterus is enlarged, of a soft consistency, at the moment of palpation it hurts even more.

Uterine fibroids

Myoma is a benign disease that arises from the muscle layer, however, often accompanied by serious consequences.

This disease often occurs in a latent form, when the size of the fibroids is still insignificant, and the only symptoms are cycle disturbance and an increase in bleeding before and during menstruation. Having reached a considerable size, fibroids deform the uterus, squeeze adjacent structures and neurovascular bundles, while the lower abdomen hurts, and the pain is pulling, arching. Sometimes, squeezing the nerves, fibroids can cause pain, extending to the right or left side.

The treatment of fibroids at the initial stages of hormone therapy, with the progression of the process, it is necessary to include surgical treatment.

Torsion of the legs of ovarian cyst (PNKYA)

PNYA is an acute surgical problem that occurs in girls suffering from single cysts or polycystic ovary syndrome.

against the background of the provoking factor (physical activity, gymnastics, turns and tilting of the body) torsion of the legs occurs, with a slight twist - no sensations may arise and the leg, unwinding returns to its original position, if the leg turns 90-100o - there is non-intensive pain, which It is a nagging character, this phenomenon may occur several weeks before the menstrual period, this is due to the compression of the venous vessels and the violation of the outflow of blood from the cyst, a full turn - blood flow through the arteries is disturbed, and And this background is rapidly developing clinic of "acute abdomen": right and left side hurts strongly and spasticly, against this background there is a strong intoxication, shock, the patient takes a forced position.

Treatment - immediate surgery with excision of a cyst without unwinding its legs.

Inflammatory diseases of the appendix, gallbladder.

Appendicitis - inflammation of the appendix, as a rule, its symptoms begin with a slight increase in temperature, weakness, loss of appetite, pain occur first at the top of the abdomen, and then, within a few hours, go down on the right side and localized in the right iliac region.

Cholecystitis - inflammation of the gallbladder walls, occurs on the background of a violation of the diet, alcohol consumption, the presence of stones in it. Pain is localized in the right side under the ribs, symptoms of intoxication are noted.

Pathology of pregnancy

Ectopic pregnancy - the development of the embryo outside the uterus (in the tubes, ovary, abdomen, neck).

A) tubal pregnancy - in case of rupture of the body, there are sharp, severe pains radiating to the left or right side, the vagina, the anus, the clinic of hemorrhagic shock.

B) ectopic pregnancy in the ovary - clinic of apoplexy,

B) in the abdominal cavity - a long course, dull clinic,

D) cervical - sharp, severe abdominal pain, clinic of hemorrhagic shock.

Placental abruption is an acute pathology characterized by severe lower abdominal pain and bloody discharge.

Features of ectopic pregnancy and placental abruption:

abrupt onset and rapid development of the clinic, delayed menstruation, “+” pregnancy tests, vaginal discharge of bloody nature,

Uterus bend

Is the deviation of the position of the uterus. The disease may be congenital or appear after pathological states of an infectious nature, such as cystitis. Patients complain of acute pain in the lower abdomen before menstruation.

Also may appear:

Severe pain in the side, which increases with palpation, Dyspareunia - painful sensations during sexual intercourse. At the same time, both one side and the entire abdominal region are painful. Tumors that begin to squeeze the organs, also causing pain

The disease is diagnosed on a gynecological examination. Full confirmation of the correctness of the diagnosis can be obtained after passing an ultrasound scan with a vaginal sensor.

If such a diagnosis was made, then first of all it is necessary to find out why the bend was formed. The main causes include atrophy of the muscular system, adhesive disease, poor development of the ligaments.

Treatment is to eliminate the root causes. If there are problems with muscles or ligaments, then they need to be strengthened through exercise. Removal of adhesions in the pelvis is achieved by dissection using surgical intervention. Laparoscopic surgery is most commonly used, but if the adhesions are active, then an additional celiac section may be required. Simultaneously with surgery, treatment with antibiotics is necessary. Also allowed physiotherapy procedures, including mud and UHF.

Treat uterus bend folk remedies is not recommended.

Inflammatory processes (endometritis, adnexitis)

Endometritis - is a strong inflammation of the mucous layer of the uterus. When it occurs, the lower part of the abdomen hurts, which is manifested by sharp and stitching sensations.

It has an acute and chronic form.

Acute form occurs after mini-abortion, childbirth, diagnostic curettage of the uterus, hysteroscopy, intrauterine manipulation. Causes of exacerbation may be the remaining placenta, removal of residual ovum, a large accumulation of blood clots. At the same time, an infection may develop, an acute inflammatory process of the inner surface of the uterus. Chronic form occurs after acutely treated. It may be due to the presence of foreign bodies in the uterus. It occurs after abortion and uterine manipulations.

Both forms are caused by various pathogens, which include viruses, incl. herpes simplex, chlamydia, toxoplasma, cytomegalovirus, fungi and radiant fungi, parasites, bacteria.

Symptoms of the acute form include:

Temperature rise to 39 °, Sharp abdominal pain, Unpleasant discharge from the genitals, Painful urination, Rapid pulse, Chills

The symptoms of the chronic form include:

Violation of the menstrual cycle, Uterine hemorrhage, Pathological bleeding with pus from the genital tract, Dull pain in the lower abdomen, Painful intercourse

You can diagnose the disease using:

Gynecological examination, Clinical analysis of blood, Bacterioscopic examination of smears, Ultrasound method, Hysteroscopy, which allows to learn structural changes in endometrium

Treatment is therapeutic in nature, is carried out in the hospital.

In acute form, antibacterial therapy should be prescribed, taking into account the sensitivity of the pathogen. For removal of intoxication, intravenous administration of saline and protein solutions is prescribed. As a painkiller used cold on the abdomen. In the chronic form, an integrated approach is used, which includes antimicrobial, fortifying, immunomodulatory and physiotherapeutic treatment. Drugs are injected both intravenously and into the uterine lining. Bleeding is eliminated with the help of hormones and aminocaproic acid solution. As a result, infectious agents are eliminated, the endometrial layer is restored.

In both cases, patients need to comply with bed rest.

As a popular recipe, they use Althea root and Leuzei, dried herbs, wormwood, and clover. The ingredients are taken in equal quantities, mixed and poured boiling water. Insist for 45 minutes, filter. Take two tablespoons 2 times a day after meals.

Adnexitis called severe inflammation of the ovaries and fallopian tubes. At the same time, the entire lower part of the abdominal cavity hurts. Patients feel sharp and stabbing pain. The disease is caused by streptococci, enterococci, fungi, viruses, staphylococci, mycobacteria of tuberculosis, chlamydia, escherichia and other pathogenic microorganisms.

The trigger factors for the occurrence or exacerbation of the condition include:

Hypothermia, Non-compliance with hygienic norms, The presence of stressful situations, Messy sexual acts, Introduction of the intrauterine device, Abortions, Complications during childbirth.

There are acute and chronic forms. Both manifestations may have a protracted course and relapses. As a complication, severe pain may occur before menstruation, aggravated during palpation.

Symptoms of the acute form include:

Sharp pains in the lower abdomen, which give into the anus and the sacrum, Chills, The appearance of mucous and purulent discharge from the genital tract, Fatigue, Abdominal distention, Disorder disorders, Patients may have a fever up to 38 °.

In most cases, the chronic form is present:

Chills, Poor general condition, Disorder of urination, in which the lower abdomen hurts, Increased temperature up to 38 °, The appearance of mucous and purulent secretions from the genital tract, menstrual disorders, metrorrhagia, algomenorrhea, oligomenorrhea

Diagnosing a disease includes:

history taking and gynecological examination, taking samples for baccosis, cervical, urethral and vaginal smears, ultrasound diagnostics, detecting inflammatory processes, diagnostic laparoscopy to determine the localization of purulent secretions, hysterosalpingography to determine the degree of obstruction of the fallopian tubes.

Treatment of the acute form often takes place in the hospital, except for bed rest and heavy drinking, includes antibacterial treatment with the help of broad-spectrum drugs. In addition, pain relievers, anti-inflammatory drugs, immunostimulating and desensitizing treatment are used. Infusion therapy may be prescribed to relieve symptoms, including intravenous administration of glucose solutions. With the development of purulent forms assigned to the operation

Treatment of the chronic form usually takes place at home and includes antibacterial, infusion, desensitizing therapy, the use of vitamins. After removing the inflammation, autohemotherapy, aloe venting, physiotherapy, UV radiation, electrophoresis, UHF-therapy, mud therapy, and vibratory massage are used.

As a folk remedy used viburnum color. Raw materials are dried and poured boiling water. Boil over low heat for 15 minutes. Take a quarter of a glass three times a day 30 minutes before meals. In the broth, you can add sugar or natural honey.

Urolithiasis disease

Is a urological disease, which results in a violation of the acid-base balance, which leads to the formation of stones in the urinary system, kidneys or bladder. More often in patients with this disease, acute pain in the lumbar spine, burning during urination, high fever appear. Also, unpleasant and pain can be observed in the lower abdomen on the right, especially increasing both during menstruation and in front of them.

A feature of this disease is a variety of symptoms: in some patients, the course of the disease is asymptomatic, even large stones can be detected by chance, in others, a recurrent nature develops, in others, it is exacerbated and becomes chronic.

The most effective method of treatment is surgery to remove stones, although, if they have been formed recently and / or are of small size, they try to solve the problem by conservative methods, such as drugs and physiotherapy.

Is an inflammatory lesion of the mucous layer of the bladder, often has an infectious nature. When this occurs, the penetration of pathogenic flora into the bladder. Mainly the causative agents of the disease are E. coli and staphylococcus, less often - fungal infections of the genus Candida, chlamydia, etc. The disease is characterized by a aching painful character with localization in the right side, in the lower abdomen.

The following factors provoke this disease:

Severe hypothermia, Circulatory disorders in the pelvis, Metabolic deterioration, Injuries received, Instrumental interventions, Anal sex

After identifying the disease using cytoscopy and a series of laboratory tests of urine, treatment begins, which is carried out by a urologist or gynecologist. It includes a course of antibiotics and antiviral drugs designed to defeat the infection, as well as vitamins and physiotherapy to strengthen the immune system.

Less common causes of pain in the lower right abdomen:

Sometimes cysts appear on the surface of the ovary — sacs filled with fluid that can grow and cause discomfort. Although they are usually harmless and can pass by themselves, they can grow, causing pain in the lower abdomen.

Lower abdominal pain, nausea, vomiting and pressure on the bladder or rectum may also be associated with its severity or fullness. Tension, bloating, and pressure in the rectum are accompanied by pain. It usually disappears with defecation and is not accompanied by additional symptoms.

This is due to the fact that a large number of organs are located in the abdominal cavity of a person, and "malfunctions" in any of them may be accompanied by pain. To be able to guess what caused the pain, it is necessary to understand such indicators as localization, nature, duration, provoking factors.

Pain in the right side during pregnancy - causes

The right side during pregnancy hurts when the growing uterus is pressing on the pelvic organs and the abdominal cavity. To clarify the cause of the pain, one should not be guided by the symptoms alone, it is very important to visit the doctor in time and conduct additional laboratory and instrumental examination.

Pain can indicate different diseases. In the morning, it hurts in my side and back. At first (about 5 years ago) there were aching pains, now it is sharper. No matter how much I went to the hospital and even the regional one, I was not diagnosed. I have such mixed feelings and I can not determine what it is and what is connected.

Pain in gynecological diseases

I myself had pains, in 3-4 days they became strong, I turned to a gynecologist, on examination I pressed and the pain went away, said that the pain was before menstruation. Mostly after eating, the pain is given in the back. All tests, examinations within normal limits. It remains only to do an MRI of the abdominal cavity, but I still do not decide. I very often began to appear pain under the right edge.

I had pain in the ribs during pregnancy. In general, as I understood, these pains can mean a lot of illnesses. Returning from a business trip, there was still “this” pain in the train. In N-sk, "identified" immediately - appendicitis! More than a month in the mornings right after the ascent, the stomach hurts, the upper central part, pains cramping, after about an hour passes, what could it be? Who to ask for help !?

And if the right side of the abdomen hurts only during menstruation, and then passes. The reason that the side hurts below, in the right side of the abdomen or behind can be any anomalies or violations of one or more of these structures. Good day! For many years, worried about the pain in the right hypochondrium.
