I have what you are feeling in both my shoulders & arm i'm on oxy but find it does nothing for that kind of pain i use Darocet for this that what the ART doctor said to use they are fing out some poeple bone pain that the oxy does't work also try to get nerv blocks and see if that helps when i have a bad bad i also will get a shot of Trodal and if that does't work i will get morphine and viseral sorry for the spelling guys hard to think having bad night
