I was lifting and felt something pop in my shoulder. Ever since then I have pain in my collarbone when lifting/doing push ups. Its been a little over 3 years and now I am in so much pain all the time. I can no longer lift or do push ups. I haven't taken an APFT in 8 months. I went to PT for my hip and shoulder pain. They focused on my hip (strained tendon) and now my shoulder. The PT diagnosed me with Thoracic Outlet Syndrome (TOS). I have pain in my collarbone constantly, upper back pain, shoulder pain, pressure in my chest, my arm goes numb, and it is hard to grip things. I am an Artillery Officer. What is the COA for this? Will I get surgery? Will I get med boarded? Thanks!
