Uterine pain is usually caused by contraction of the uterus. The more common cause is dysmenorrhea during menstruation, most of which is a normal physiological condition and does not require special treatment, and a few cases may be related to some gynecological diseases. The common clinical factors leading to uterine pain are as follows: 1. Dysmenorrhea: uterine pain is mostly caused by dysmenorrhea during menstruation, pelvic congestion and prostaglandin release during menstruation, resulting in uterine contraction causing pain, this condition will generally be relieved after rest; if dysmenorrhea is heavy, symptomatic treatment with painkillers such as prostaglandin inhibitors, ibuprofen and acetaminophen can be applied under the guidance of a physician if necessary. If the uterus has persistent pain or is accompanied by other discomforts, it is necessary to consult a doctor in a timely manner and do special examinations such as gynecology and ultrasound to rule out other pathologies. 2. Pelvic inflammatory disease: Pelvic inflammatory disease is an infectious disease of the pelvis that sometimes affects the uterus and causes persistent pain in the uterus. Patients are often accompanied by symptoms such as fever, uterine pressure and painful thickening and pressure in the adnexal area, and some patients may also develop pelvic effusion. Patients with pelvic inflammatory disease should be given anti-infection treatment and, if necessary, combined with herbal treatment to activate blood circulation and remove blood stasis; 3. Endometriosis: for example, pelvic endometriosis nodules, ovarian chocolate cysts or adenomyosis, etc., which usually appear as painful nodules in the posterior vaginal vault and uterosacral ligament areas, can lead to uterine pain. Clinical treatment for endometriosis is mostly individualized, such as the use of the Manned Ring, short-term oral contraceptive pills, prostaglandin inhibitors, mifepristone and other treatments under the guidance of a doctor, and if necessary, surgical excision according to the progress of the disease; 4. Other diseases: for example, endometritis, tubal infection, ovarian infection, etc. can cause pain in the uterus, so it is recommended that patients should go to the hospital in time to seek medical advice and get the right treatment after clarifying the cause.
