Hello, I am inquiring about whether the pain I ve been feeling in my left ankle/foot for the last 4 months is Osteoarthrtis or something else? It is very painful at most times. Most painful when I put weight on after either sitting or lying down. Even after sitting and driving my car and then getting out of it to walk. I am a 46 year old woman. I work full time and stand on my feet for long periods of time, I am a cosmetologist. It seems to be more strangely painful after sitting/lying down than standing.
