The reasons for the symptoms of ankle pain when walking are as follows: 1. Ligament sprains and other causes, such as when strenuous exercise causes ligament sprains, which can lead to ankle pain and local soft tissue swelling; 2. Osteoarthritis, osteophytes, gout, rheumatoid arthritis and other diseases can also lead to ankle pain. Pay attention to rest and avoid strenuous exercise. If the ankle pain is caused by trauma, to reduce the swelling, you can apply cold compresses with ice packs in the early stage, and after more than 24 hours, you can use hot towels for warm compresses or physical therapy to promote blood circulation and relieve pain. If the symptoms do not improve, you need to go to the hospital to check the ankle X-ray and blood uric acid, rheumatoid factor and other tests to exclude the ankle pain caused by gout and rheumatoid arthritis, etc. Only with a clear diagnosis can we carry out targeted treatment.
