What Causes Pain In Lower Leg?

I am a 48 year old woman, approximately 190 lbs and I fell in April 2011 and ended up with massive bruising and swelling in my lower right leg. The whole lower leg swelled and bruised all the way to and including my ankle and foot. Went to the Doctor about a week later because it seemed to get worse and the doctor said it was a hematoma. Put me on 800mg Ibuprofen and a diuretic(sorry, I can't remember what it was). Most of the swelling and bruising went away approximately a month or so later but I still had a lot of pain. Went back to the doctor and they did xrays of my leg to rule out any kind of fracture. It is now going on 3 months and I still have moderate pain all the time and it gets worse with exercise. Should I go back and have the Doctor rule out any soft tissue problems? Sorry this is long.
