Be careful and watch for side effects...
I am severely allergic to Fentanyl but didn't know what was going on for a few days... was going in severe anaphylactic when my Chiropractor noticed the allergic reaction!!!
I hope it works for you... it does for many... but as you know.. with RSD.. no two of us are the same...and don't react the same to medicines.
