Around november of 2013 I got this really bad right shoulder pain that went slightly up into my neck. On the 1 to 10 scale it was a 9. Doc said it was shoulder tendinitis and gave me naproxen. It helped but I was still in pain for about a week, then it slowly went away. It acted up every now and then but almost 2 weeks ago it came back like the 1st time around. But this time I have pain and a tingly numbness in my 4th and 5th finger on both hands, the back of my hands, and my wrists as well as my left shoulder is now starting to hurt like my right one. I'm 15 and do jrotc and go to a public military high school. School and jrotc starts in about 2 weeks and I can barely do 10 push ups cause it hurts. Any ideas what might be going on?
