What medication helps for pain in upper right side of the back ?

Depends...: This completely depends on what the nature of the pain might be. Pain in upper right side of back can be anything from muscle strain, rib issues, to liver or gallbladder issues. Its difficult to recommend any medications without being sure where the pain is coming from. This should be assessed by a physical exam and workup to rule out any internal issues. Hope this helps and best of luck!
