IT BUUUUURNS.
I don't know what the heck I did, but a few days ago, my back started hurting... and today the pain has multiplied tenfold and now, I can't move my left arm without my back feeling as if it were stabbed. I can't lean in any direction, and it hurts like hell to breathe in deeply... did I crush a vertebrae or something? And should I go to the doctor?
