pain
"I have been on Opana Er 60mg 3x a day for over a year now for chronic back pain.  It is wonderful.  Nothing has ever worked for me like it has.  Not fentanyl patches, not oxys, nothing.  I suggest any of you have a genetic test done by your pain doctor. I did.  It allows your doctor to be able to tell what pain meds work for you the best.  It isn't always about what med is the strongest, its about what your body will use."
