Ankle tendon pain is clinically known as pain in the tendons and ligaments around the ankle joint. The common causes of walking pain on the inner side of the ankle include trauma, gout, tenosynovitis, etc. The treatments include physical therapy, medication, surgery, and so on. 1. Trauma: caused by the impact of external force on the inner side of the ankle, or high intensity exercise. If the symptoms are mild, local physical therapy, such as hot compresses on the inner side of the ankle, can be used. If the pain is severe or accompanied by fracture, external fixation or surgical internal fixation is needed. 2. Gout: High purine food intake may cause hyperuricemia, leading to gout. Uric acid level should be checked in time, and drugs such as ibuprofen for pain relief and colchicine can be used to regulate uric acid level. The above drugs should be used under the guidance of a doctor, avoid taking them on your own. 3. Tendinitis: If the patient’s foot joints have long-term activities and exertion or often wear ill-fitting shoes, it may cause tendon inflammation, resulting in pain on the inner side of the ankle, which requires systematic examination, reduction of activities, local physiotherapy, oral celecoxib and other non-steroidal anti-inflammatory drugs, and surgical treatment or closure when the condition is aggravated. If the pain on the inner side of the ankle is serious, you should go to the hospital for treatment in time to avoid delaying the condition.
