Since yesterday morning, my upper left back has been hurting me because I slept on it wrong. Yesterday, it felt like a muscle knot and it felt more relieved when rubbed. But today, it still hurts a lot but it feels like a pinched nerve. I don’t know which one it is, so I don’t know how to treat it. HELP!!! Any advice is accepted. Thanks in advance!

I have a pinched nerve between my shoulder blades that had been bothering me since yesterday morning. Its painful when I turn my head, and I had trouble sleeping last night because I was so uncomfortable.

Any suggestions about how to eleviate the pain, and/or fix a pinched nerve?
