I had swollen ankles for quite a few years. However, recently my ankles swell to a very large size, and my legs and feet swell, too. I prop my legs and feet at night when I am in bed, and in the mornng the swelling goes down, but within a few hours they are back, big again.
Hello, It could be a sprain or contusion. Consult an orthopedic and plan for an MRI scan to make a diagnosis. Hope I have answered your query. Let me know if I can assist you further.
