I have been have horrible shoulder pain since June of 2012 which has gotten progressively worse. The pain goes up my neck an is in my back too. It has gotten to the point that I haven't been able to sleep, I can't concentrate and I just don't want to do anything because it hurts. My X-ray and MRI of my shoulder came back normal. I have a lot of pain and loss of range of motion. What could it be. Please help. I want my life back! Also I go to a chiropractor every week so I am not put of alignment.
