I will further expand, I used to weight lift stopped for about 11 months due to wrist surgery, about a year or so ago I was shrugging about 100kg and felt a cold sensation on my neck where the pain now occurs, it was like getting an injection into the muscle slow moving out of a cold feeling across the muscle from my neck about an inch into the muscle towards my shoulder, I stopped lifting stright away and stretched the muscle, there was no pain in the muscle after this but this injury has been here on and off for over a year now

I know if I go to my doctor he will give me pain killers and tell me to rest it, I have tried resting it for weeks and it has not helped, any help in this matter would be great I would like a diagnosis before I go to my doctor, so I can ask for what scans are needed etc, to get this problem sorted I would hate to have this all my life.
