Ankle swelling should be divided into the following two cases: 1. If it is due to trauma, that is, swelling after ankle sprain. The correct treatment should be, firstly, to ensure that the ankle joint is braked, that is, not to walk. 2. If the swelling of the ankle joint is not due to trauma, it is likely to be an attack of gouty arthritis. The correct way to deal with this is to ensure that the ankle joint is braked and to go to the hospital as soon as possible to have a blood test to see if the blood uric acid is elevated. If it is elevated, you should follow the symptomatic treatment of gouty arthritis, commonly used drugs include non-steroidal anti-inflammatory and analgesic drugs, together with drugs to alkalize urine, and you should pay attention to the avoidance of food.
