Ankle pain without significant swelling Pain when walking but no obvious abnormalities on radiographs may be related to mild ankle sprains and early arthritis. In mild ankle sprains, there may be no obvious bleeding or swelling of the tissues, and the pain may be caused by pulling on the injured area around the ankle joint when walking. In the radiographic examination, since the injury site is a non-bony structure, it can be shown that the radiographs are normal. Ankle arthritis, such as osteoarthritis, rheumatoid arthritis, etc., can cause damage to the articular cartilage and synovial membrane in the early stage, which will cause pain when walking, and there is usually no obvious swelling. The non-bone structure and articular cartilage do not show up clearly in the radiographs, so the radiographs may show up as normal. Physiologic ankle pain can occur after strenuous physical activity such as running and climbing, and the above symptoms can also occur. If the ankle joint pain without obvious swelling, when walking pain radiography shows normal, we recommend that the patient go to the hospital to improve the examination and receive regular treatment.
