I started getting monster headaches about 14 months after the onset of RSD. In fact, I can remember the exact day - October 18, 1987

I spent as much time with doctors looking for the cause of migraines as looking for the cause of the RSD.

A do notice a corrolation between a flare-up of the RSD and a more severe headache. Sometimes one is the warning of the other. Too bad I still can't do anything about either. (Not too effectively, anyway.)
