Hello. In october, I had a ACDF performed on my C5-6, C6-7 vertebrae. It look away the pain in my shoulder blade/back and my left arm. About 3 weeks ago the front of my shoulder socket and trap muscle begin aching. Sometimes it is unbearable and my shoulder actually feels like its burning. I went back to my neurosurgeon, and they said it had nothing to do with my neck and it may be bursitis or arthritis. The pain seems to move from my front of the shoulder to my trap muscle. When I become immobile, it feels better. As soon as I get up and start to move, the pain returns... Any ideas?
