During hysteroscopy, patients feel little to no pain. Some patients may experience a sensation of lower abdominal distension or vague pain when the mirror enters the cervical canal to minimize irritation, but it can be tolerated. For individual patients who are more nervous or need to undergo microscopic surgery, local or intravenous cervical anesthesia can also be administered, which can effectively reduce the pain sensation. Hysteroscopy has a magnifying effect on the observed area and is the preferred examination method for gynecological bleeding disorders and intrauterine lesions. If patients feel pain after hysteroscopy, they can take proper rest, prohibit sexual intercourse and bathing for one month, or give appropriate local hot compresses to improve the pain symptoms. Usually the pain will subside or disappear after 24 hours, and patients need not worry too much. In case of postoperative infection, oral antibiotics can be administered as prescribed by the doctor. If abdominal pain and increased vaginal bleeding occur, prompt medical treatment is needed to control the bleeding.
