ItHurts!

I wonder if any of you can relate to this. I wont mention my problems history for now or this post will get really long. Anyway I have been having these wierd shoulder pains for about 4 months now. They are off and on but they occur daily. The pain runs along a thin line from my spine at about T4 to the top of the shoulder blade. it then occurs on the shoulder blade and down it. The pain is mainly on the shoulder blade and it feels like a sharp muscle tear or strain. it also occurs right on the side of T4. It is mainly on the left side but is also occasionally felt on the right. They usually hurt at about the same time. The thin muscle i described is gets tight and i have been treating it with a tennis ball to work the knots out. It feels like a serious problem and i am afraid to work out with it. Ive gone to many doctors each with a different diagnosis. Starting from first to latest. 1. muscle strain 2. pinched nerve 3. Not pinched nerve. Myofascial pain syndrome 4. scoliosis 5. x-ray shows no scoliosis. muscle strain.
I have also considered things such as herniated disk because i cant stop looking things up and i have a vivid imagination. I can mistake food posioning for an ulcer. Anyway my problem occurs mostly when waking up. I cant make any sudden movements when i wake up or it starts up. I need a firm bed and i must sleep on my less painful side and i need to use the fetal position. The bottom of my bed in my dorm is basically a metal hamock. I sink right in. I had to use books to support it from underneath and for some reason that helps. How pathetic is that! Anyway i guess if it works. The pain is sharp but there is no tingling. it isnt strong but it is annoying. I dont have pain any where else except occasionally in my chest when i bend over really far and then lean back up. It is weak and it lasts about a second. Certain other shoulder and back movements have the same effect. I will say that it started with 2 muscle injurys spaced out about 1 and 1/2 years. it was much smaller problem the first time but changed after bench press injury the second time 4 months ago. Too many possibilities but i cant get anyone to figure it out. im afraid it is a spine problem but nothing showed up on the x-ray. Any one with any answers or recomendations? Im getting fat and i want to work out again. Im just too confused. I guess i just looked into it too much.
