I agree with a lot of you that everyone with RSD is different. Just look at all the different classes of medications we are all on.
I've only been on one narcotic which is Methadone. All I know is that my pain skyrocketed on Methadone. In fact my left foot has never been the same since then and it has been about 9 months. My Neurologist had no idea why that happened and could offer no explanation. Since that episode I've been too nervous to try another narcotic.
