The cause of thigh root pain after hysterectomy is mostly due to inflammation of pelvic tissues after surgery. In addition, checking the lymphatic tissues at the thigh root during the surgery to cause adhesion or reducing the amount of activity after the surgery can also cause pain. 1. Inflammatory changes in pelvic tissues after surgery or formation of effusion causing local compression can cause thigh root pain. 2. While performing hysterectomy for endometrial cancer, the lymphatic tissues at the root of thigh need to be checked at the same time, which means that the surgery will affect the lymph at the root of thigh and may also form pain. 3. Pain may also be induced by prolonged bed rest and reduced exercise after surgical treatment, resulting in thigh muscles and nerves not getting sufficient exercise and activity. It is recommended that patients get out of bed properly, take a walk indoors, and do not exert themselves too much. In addition, if there is no wound on the root of the thigh, you can also apply hot compresses to relieve the pain.
