Most patients do not experience ovulation pain, which is manifested by small abdominal distension or back pain during ovulation due to changes in hormone levels and changes in pelvic blood circulation. Ovulation pain can occur in a small number of patients, mostly due to inflammatory diseases of the pelvis or various diseases such as endometriosis. If a patient has ovulation pain that is particularly pronounced and affects normal work and life, an internal gynecological examination and ultrasound are required. Through these two basic examinations, it can be generally determined whether the patient has inflammation of the ovaries, inflammation of the adnexal area or pelvic stasis syndrome, endometriosis, etc. If these underlying diseases are present, treatment must be given for the underlying diseases. If these underlying diseases are not detected, contraceptive pills such as Daimler-35 or Ursine can be taken to treat the abdominal pain during ovulation.
