Can anyone advise on what could be causing my shoulder, back and neck pain?

Hi I've had a bad pain that in my shoulder blade about three years ago. It was made worse on movement that calmed down when I stopped moving. It gradually went away by itself but last year it came back with a vengeance and is gradually getting worse. Now when I tell my neck to the left I get a sharp pain in my shoulder blade. My neck hurts pretty much constantly. My breastbone and shoulders hurt too. My ribs and sternum at the front are painful to the touch. When I do any kind of activity that involves my arms, the pain builds up and becomes unbearable. I wake up really stiff and in pain every day and i loosen up after about 3hours. No painkillers enable me to still work through this pain and the only thing that helps is actually to stop moving. I have seen a physio who has no idea what it could be. An Orthopaedic doctor suggested it could be fibromyalgia. I saw an osteopath who after four sessions said that they could no longer treat me as they suspected I had Tietzes Syndrome, and a Doctor at the Pain Clinic suggested I was stressed and my nerves were firing off signals all over the place. The only test I've had is an X Ray and that showed that my the curve in my Cervical Spine had been reversed in keeping with muscle spasm. The pain has become unbearable and it is seriously affecting my quality of life. I had to quit a college course and I am off sick after starting a new job only a week ago. I'm not sure what to do, or where to go next. Can anyone help?
