The vast majority of people will not experience pain if the hysteroscopy is performed alone. Individuals who are relatively sensitive may experience a vague pain in the lower abdomen due to the stimulation of uterine contractions caused by the entry of the hysteroscope through the uterine cavity, but most of the pain will go away after about 30 minutes or one hour. If the procedure is done through a hysteroscope, it may cause pain in the lower abdomen, which will not last more than 24 hours. If the abdominal pain after hysteroscopy or surgery increases progressively, or the duration of abdominal pain is prolonged, it is necessary to go to the hospital for a follow-up examination, the main purpose is: 1, to exclude the possibility of infection, if there is an infection, it will be accompanied by pain in the lower abdomen and discharge odor, and there may be a fever. 2, need to rule out the possibility of perforation of the uterus.
