Soreness in the lower back and legs after hysteroscopic electrosurgery is usually a normal condition due to the abnormal stimulation of the uterine area by the hysteroscopic surgery, which will be relieved with time. Hysteroscopic electrosurgery is usually an operation to remove endometrial polyps or endometrium from the uterus of the body, which will cause strong stimulation of the body, and may cause pelvic congestion, which may result in abdominal pain, lower back pain and other adverse reactions, which are generally normal. If the patient does not get relief from the symptoms of lower back pain after hysteroscopic electrosurgery or if other problems occur, he/she should consult the doctor in time to clarify the cause of the disease and under the doctor’s guidance, he/she should undergo treatment.
