There are many causes of swollen and painful ankles, including soft tissue degeneration after trauma, acute and chronic synovitis after ankle sprain, osteoarticular tuberculosis, osteoarticular infection, and even joint tumors, the most common of which is rheumatoid arthritis, and gouty arthritis, all of which can cause swelling of the joint. The specific causes need to be examined at the hospital, and the corresponding diseases can be diagnosed according to the results of the film and laboratory tests, so that corresponding treatment can be done. For example, if the swelling is caused by a sprain, oral medication to activate blood stasis and reduce swelling, braking and rest will reduce and improve; if it is bone tuberculosis, anti-tuberculosis medication should be given; if it is an infection, the so-called antimicrobial agent should be given; if it is a tumor, conservative or surgical treatment can be given according to the difference between benign and malignant; if it is gout or rheumatoid arthritis, symptomatic medication should be given according to the clinical condition.
