my ankles swell often,(as a result of a 20year old injury) especially when I travel out of the country. lately, not only has it gotten swollen, but it is very painful, and is not allowing me to walk with ease. I ve tried soaking it in warm water, as well as drinking parsley boiled with water, which helped in the past. what do you think is causing this pain, and are there any ways to ease or get rid of the pain?
