To an RSD sufferer: I have had RSD for 3.5 years. I know what you are going through as I am a difficult case because I am allergic to all of the pain meds that are out there. Hang in there. You may want to get a second opinion and be sure that your regular physician is also in agreement with the pain doctor so that you can continue to receive the blocks. It sounds like they work for you!:) Keep your chin up and if you would like to talk, e-mail me! When you have this disease, no one really understands it unless they have it!
