Hi Rachel...my first suggestion is to never ever ever ever Google symptoms. Doing that almost put me in the looney bin. The worst case scenario always pops up first. All of your symptoms are consistent with fibro...all of them. I have every one of them that you mentioned and yes...I have thought about all kinds of horrible disease this could be. I have 'numb' sensations everywhere...and tingling, crawling, pin prick...bee sting sensations...you name it. My hips ache so badly I limp. And I can't rotate my left shoulder. By any chance do you have scoliosis? I do and that causes the numb/tingling in my back because of my posture...right where the bra (if I wore one) would be.
I'm no doctor but I think this is just fibro. Take a deep breath. I had a friend with bone C that didn't have any pain so you can't base it on that.
