If a woman has stomach pain when she has her period and the pain is obvious and affects her daily life or work, she may consider using painkillers to relieve the symptoms, such as oral anti-inflammatory pain, ibuprofen and other drugs, or using diclofenac sodium suppositories in the anus and intramuscular pain injections to relieve menstrual pain. In addition, you may consider bed rest, applying warm compresses or hot water bags to the lower abdomen and rubbing the lower abdomen gently with your hands. Try not to eat spicy, stimulating or cold food for a week before your period, try not to touch cold water, and don’t get emotional or stressed. If a woman has very obvious menstrual pain and the pain is unbearable, it is best to go to the hospital for an internal gynecological examination after the menstruation clears to see if there is any lifting pain in the cervix and pressure pain in the lower abdomen. See an obstetrician and gynecologist for an internal examination to see if the uterus is fixed and an ultrasound to determine if there is pelvic endometriosis or chocolate cysts. If you have these abnormal symptoms, you can also consider elective surgery.
