My foot doctor said I have arthritis in my ankles . last year I broke one of my ankles before that they were always hurting because I was always spraining them due to having very flat feet. The ankle that I did not break is worst than the one that was broken. The pain is very bad when I walk up stairs my doctor said the bones are rubbing together. I take 800 ml Ibuprophen it doesnt help at all. what else can I try that may be of help?
