Working to get full ROM back I have pretty severe pain in the right shoulder 100% of the time . There is no relief with ice, or any of the pain relievers I have been given. I feel as f I am going to go insane with zero pain relief ever. Is there any good severe pain medication that I can still try. I have itching and rash with: hydro codone/norco/Percocet/Vicodin Tramadol doesn't do anything at all, ibuprofen either.
