I've been taking 200 mg of Topamax for a long time. It helps enormously with my head pain. When I tried to taper off of it, my migraines came back with a vengeance.

My RSD started in my right shoulder, from a brachial plexus stretch injury and a torn rotator cuff, then 2 repair surgeries. It spread to my cervical spine and occipital area, I have a LOT of trouble with my head. I also have RSD in my right leg and I suspect in parts of my feet and hands - there are ongoing issues that tons of ketamine and exercise helps to keep at moderate levels for the most part.

I also take Fiorcet for my head pain (several times a day) and Frova (a triptan). There are others, but those are the ones that I use for my head. And I will put Voltaren gel in my hair on my scalp when it throbs, and that helps too....

Try to keep moving if you can. I find that its been the best for me.

Good luck! Sandy
