I've had back pain under my right shoulder blade for 7 months. What could it be if all tests (MRI, CT, X-rays) came back negative?
I saw a chiropractor for 3 months. I did physical therapy for 3 more months. I have practiced yoga and other exercises weekly for years. This pain is worst when sitting. I work on a computer for a living but have ample back support and good posture. Please help!! All out of ideas.
