This is my first post , i'm serving in the military and the medical where i'm at has proven itself very difficult to work with. I've been having pain in my left arm since mid december. This pain originally started in my left tricep area and worked its way to my wrist over about a month. The pain went away gradually and I went to a ground fighting course this past week. I was medically dropped because of pain in my left shoulder almost at the base of my neck going all the way to my left wrist. The pain is not as bad if I stand up or if I lay on my left side. If I sit against my back the pain can be almost a 10 out of 10 on the pain scale. I've been told it's more then likely a pinched nerve. Does anyone have any ideas or suggestions?Anything at this point would be helpful . Thank you!
