Hello. I am a 52 year old male, reasonably healthy, though I have osteopenia and I take Lipitor for border-line high cholesterol. Recently, I have been experiencing leg pain whenever I cross my legs (the pain is in the hip) or sit Indian-style on the floor. I am also experiencing shin splints at night when I sleep. I have no trouble standing or sitting for a long period of time, and I do not have trouble breathing when I walk. Aging? Arthritis? Blood vessels narrowing? I will see my doctor soon for a regular check up so I am sure I will receive the proper diagnosis then. But what do you think, sir?
