Menstrual cramps can occur during or just before your period. The pain from these cramps can range from mild to severe. It can involve the lower belly, back, or thighs. You may also have headaches, nausea, dizziness, fainting, diarrhea, or constipation with your cramps.During the menstrual cycle, the lining of the uterus produces a hormone called prostaglandin. This hormone causes the uterus to contract, often with pain. If you have severe cramps, you may be producing higher-than-normal amounts of prostaglandin. Or you may be more sensitive to its effects.Primary dysmenorrhea is a term used to describe painful menstrual cramping that isn't caused by a medical problem. It often starts during the teen years, when periods first start. But the pain often improves as you get older.Secondary dysmenorrhea is a term used to describe painful menstrual cramping that's caused by a physical problem other than menstruation. Problems that can cause this type of cramping include:A condition in which cells that look and act like the cells of the lining of the uterus (endometrium) are found in other parts of the belly cavity (endometriosis) or grow into the muscular tissue of the uterine wall (adenomyosis). Pain usually occurs 1 to 2 days before menstrual bleeding starts. It continues through the period.Growths in the pelvis that aren't cancer (benign growths). This includes ovarian cysts, cervical or uterine polyps, and fibroids. Pelvic infections. They can cause worse pain and cramping in your belly during your period.Using an intrauterine device (IUD). An IUD may cause worse cramping during your period for the first few months you use it. If menstrual cramps persist or get worse, talk to your doctor.Structural problems that were present at birth (congenital). This includes narrowing of the lower part of the uterus that opens into the vagina (cervix).Menstrual-type cramps may occur after a medical procedure. Examples are cautery, cryotherapy, conization, radiation, endometrial biopsy, and IUD insertion.Check Your SymptomsDo you have menstrual cramps?Menstrual cramps can affect the lower belly, back, and thighs.YesMenstrual crampsNoMenstrual crampsHow old are you?Less than 12 yearsLess than 12 years12 years or older12 years or olderAre you male or female?MaleMaleFemaleFemaleWhy do we ask this question?The medical assessment of symptoms is based on the body parts you have.If you are transgender or nonbinary, choose the sex that matches the body parts (such as ovaries, testes, prostate, breasts, penis, or vagina) you now have in the area where you are having symptoms.If your symptoms aren’t related to those organs, you can choose the gender you identify with.If you have some organs of both sexes, you may need to go through this triage tool twice (once as "male" and once as "female").
