question: Am in excrutiating pain in my shoulders with very limited arm movements, also my hip joints and am finding it very difficult to walk. The x-rays of my shoulders were normal in the E.R. Have a history of breast cancer..........The doctor suggests a pet scan of my whole body but if the x rays were normal, do I need this and how do I deal with excruiating pain....I have tried anti inflammatory drugs and lots of advil but nothing works. Nights are proving horrible as I am woken up my pain in my shoulders and legs most of the night.
