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&#039;t always about what med is the strongest, its about what your body will use."
