Symptoms of foot osteoarthritis may include significant swelling, pain, and limited movement in the joint area. If the foot osteoarthritis is caused by exertion or over-exercise, it can be treated by physical therapy, medication and surgery. If prolonged exertion or over-exercise is involved, it may lead to osteomalacia and narrowing of the joint space in the ankle joint of the foot, causing osteitis of the foot, with symptoms such as swelling and pain in the joint, and limited movement. Treatment methods: 1. Physiotherapy: If the patient has symptoms of osteoarthritis of the foot, hot towels or hot water bags can be used to apply hot compresses to the ankle joint area of the foot to promote local blood circulation, which is conducive to the absorption of swelling and pain relief. 2. Medication: If the pain symptoms of osteoarthritis of the foot are obvious, you can take non-steroidal anti-inflammatory drugs such as ibuprofen, celecoxib, diclofenac sodium, etc., to help relieve the symptoms. 3. Surgery: If osteitis of the foot is more serious and symptoms such as limited joint movement occur, surgery can be taken as a treatment. It is recommended to use medication under the guidance of a doctor, not blindly self-medication to avoid adverse effects.
