The pain began in my shoulder about five months ago. Since then it has moved to my right shoulder, then down my back. Now, I feel as though it's all in my back just along the right side of my spine. It is intense sharp pain when I use my back. E.g.. When I'm lying down and try to get up. Or sometimes just when I'm walking, I'll even fall... It almost feels like a pinched nerve or something... I have gone through physical therapy, chiropractics, and now I'm taking vimovo. This seems endless. Help?

Pinched nerve ?
