Pain in the abdomen every night is considered to be caused by endometritis or pelvic inflammatory disease. It can cause hidden pain in the small abdomen, soreness and swelling in the lower back, accompanied by increased vaginal discharge and yellowing. Uterine fibroids and ovarian cysts can also cause vague pain in the abdomen and may be accompanied by frequent urination symptoms. The diagnosis can be clarified by internal gynecological examination and ultrasound examination of uterine adnexa. Gynecological double diagnosis, pressure pain in the uterus and pelvic fluid, indicating inflammation, requires active anti-inflammatory and symptomatic treatment, either intravenous infusion or oral anti-inflammatory drugs, which can provide significant relief after treatment. For ovarian cysts and uterine fibroids, depending on the size of the mass, choose surgical treatment or conservative treatment.
