My left hip has very sharp pains when I walk or flex. It has been going on for 12 days. I thought maybe I had hip bursitis, but after seeing Dr he had me get an Xray and they said no fracture or dislocation, but I had moderate ostoarithritis. Told he could give me a pain prescription, but I only take Ibuprofin when needed. Could I have tendonitis, or what kind of a doctor, should I go to?
