Soreness on both sides of the waist one month after hysterectomy or ovariectomy may be caused by physical weakness, abnormal direction of blood vessels and nerves, and bone loss. 1. Physical weakness: one month after hysterectomy, some women are physically weaker and may experience soreness on both sides of the waist if they lie in bed for a longer period of time. 2. Abnormalization of blood vessels and nerves: After hysterectomy or ovariectomy, the ligaments connecting the uterus will be sewn together again, leading to a void in the pelvis, which will change the direction of blood vessels and nerves, and cause the symptoms of lumbar soreness. 3. Bone loss: Most of the estrogen in a woman’s body is secreted by the ovaries. After the removal of the uterus and ovaries, the level of estrogen in the body will decrease, resulting in bone loss, and some women will also have the symptom of lumbar soreness. One month after uterine and ovary removal, if you have symptoms of back pain, it is recommended that you go to the hospital in a timely manner to get a clear picture of the cause of the problem, and then follow the doctor’s instructions for the correct treatment.
