Without a word of exaggeration, I've never had any back pain issues previously - I was fine all my life, then one day I wake up and I have debilitating pain in my upper back. Literally fine one day, I sleep one night as normal, the next morning - agony. That was about 3 months ago, and every day since then I've had upper back pain like I was suffering from it my whole life. If I breathe deeply, I get a wave of pain across my upper back that's shocking. I have to go through a ritual of painful stretching for about 45 minutes to get to a point where I can move again without wincing in pain. Pain killers do nothing to help. After a few hours, the pain diminishes such that I can go on with my day, but after sleeping (on 3 different beds over different nights) it all starts over again.
One day fine, the next day - this, and every day since. Thoughts?
