Hi Bob. Thanks for the reply. The weakness is more of a general heaviness with overhead movement. If I had to pinpoint it I'd say the shoulder. I did not do anything in particular. I just began having some upper back pain one day and it progressed rapidly. I don't really notice any discoloration of the affected arm. Though the veins are darker on the symptomatic arm and my hand turned colors and became weak during a roo's test.

If I sit upright for a few minutes, my shoulder and neck will tighten and twitch which then causes the TOS like symptoms. The left sided upper back pain is the only constant. If I stretch my neck it feels restricted in the same area.

Would any additional diagnostic tests be helpful? What is the treatmebt for a misaligned thoracic disk?

Please feel free to ask me anything else.
