Hi I Have Been Leg Pains For Over A Year.

Hi I have been leg pains for over a year. My heart doctor (I have triple bypass a couple years ago) thought it was statins but ruled that out. Then ortho dr. told me I have arthritis in one of my hips and thought that could cause leg pain. He prescribed an inflammatory medicine and no longer have hip pain or goin pain which I could be barely with. I am concerned because through all of this I still have the burning and throbbing pain and sometime sharp pain in my right leg/shin. So bad I can't sleep and pain medicines sometimes do not help it. I am very nervous of what it could be.
