The foot is broken and the tendon pain inside can be treated in the following ways: 1. Confirm the diagnosis of joint injury: First of all, it must be clear by X-ray and MRI whether there is a fracture or ligament injury of the ankle joint. If there is any of the above, it must be fixed with a cast or brace for about six weeks. The lower limb should be elevated during immobilization to help the swelling of the limb go down, which will relieve pain and soft tissue swelling. During the fixation period, you cannot walk with the cast under weight, otherwise it will easily cause the cast brake to fail and the ligament and bone repair to fail. 2. Exclude joint injury: If fracture or ankle ligament injury is ruled out through imaging examination, you can use elastic bandage to wrap around the joint to protect it. The repair period of soft tissue injury is usually about two weeks, and the patient should try to reduce the weight-bearing walking on the ground within two weeks.
