Hard to concentrate when I am in so much pain

Hard to concentrate when I am in so much pain---my shoulders keep disappearing, and the pain is neverending. Even typing on a small netbook causes pain. I suppose the torturers like me with no shoulders and in constant pain. I find it too hard to concentrate on anything, and do not have enough energy to take care of routine business. I sleep a lot, but even in my sleep, my shoulders hurt.
