Severe redness of the palm, particularly the heel (at the wrist, opposite the thumb - mine can spread up to the little finger, and even envelope the entire palm except the center) with searing, burning pain has always been my primary RSD symptom for nearly 20 years. My RSD was initially in my left hand, but it developed in the right maybe 15 years ago.

Have your Drs suggested/recommended Neurontin? It was just finishing clinicals when I got RSD and not available. 2-3 years later, my Mom had a significant stroke. Her right palm was extremely red, her right forearm very swollen, and she was vocal in her pain. No one could even touch her on the right. They diagnosed RSD brought on by the stroke. Her Drs put her on Neurontin and her relief was immediate. When I got home (she's in Oregon), I inquired about Neurontin and have been on it since.

I was originally on 600-900 mg (I think) for RSD management. I am now on 3600 mg daily because of added neuropathy from a recent, catastrophic illness. I'm not aware of any side affects, for me, over the years or from the increases. Perhaps it would be worth your time to ask about it? RSD ranges from a slightly annoying, nipping puppy, to an enraged Grizzly ripping you apart. RSD is exactly like Forrest Gump's box of chocolates. The very best of luck to you.
