Hello, have had a pain in my ankle for over a month. It is sensitive to the touch, gives off a very "sharp" pain sensation and it hurts to walk on after being on it for a short period of time. At first it was just my ankle area, but know the pain is gong up the front of my leg to my knee. I haven't been to the doctor because of financial matters. If anyone could give me a possible idea of what it could possibly be that would be great!
