Julie, I am so sorry that you have been affected by this monster called RSD. It is always so sad to meet someone new to this situation. I have had chronic headaches for as long as I can remember. Sometimes they are really bad though I would never classify them as migraines. I take topomax. But I take it for my headaches & hopefully to work as a nerve block to help the RSD. I hope you find something to help you.
Hugs, Denny
