I have RSD/CRPS and had a great experience with Cymbalta, but after a few months it became impossible to continue taking it due to severe stomach pain. Over the years I've tried many meds for nerve pain, and Cymbalta was the best of the bunch. I even retried it a year or so after to see if I could figure out a way to avoid the stomach issue, but it was still impossible.

Hopefully you'll have a positive response! Good luck.
