Neko,
Welcome to the forum. Sorry to hear about your CRPS.
I have CRPS in my foot (diagnosed in 2008) and am on amitriptyline, neurontin, naproxen sodium and trazadone (for sleep).
I really don't have much to add to Catra's comprehensive and accurate post. I agree with everything in that post. Proper pain management, physical therapy, no ice, keep it moving as best you can.
Get plenty of opinions on your condition and how to treat it. Know this....CRPS is widely misunderstood, even among professionals! It is highly recommended that you assemble a "team" of professionals, as a multi-disciplinary approach is the best for this condition. My team consists of my podiatrist who is the team leader, my GP, pain management doctor, physical therapist, chiropractor and I use a massage therapist periodically.
Here are a few links that you should check out that may help you. Lots of good information. Even though Dr. Hooshmand is no longer practicing, his advice is still very pertinent. Good luck and keep us posted!
