I don't know if it's just me but, I can't sleep on my left side, my hop feels like it's moving out of its socket, so painful. I sleep on my right side but my shoulder wakes me with pain so I try to sleep on my back, but the headache is torture. I only get it while sleeping on my back. It's like my head is cemented to the pillow. I can't move a muscle. The pain when trying to move leaves me a wreck. Crying like a baby. Anyone else have this? I am on Morphine, aspirin, quinine, severadol, nortriptilyne, arcoxia, statin, mertazapine, senna, and certrizine.
