Ali--- just in caase you didn't see it, I bumped up a post for you few a few days ago another post about botox and dystonia/RSD that was orginally posted a few weeks ago.....
And just to re iterate what I mentioned on that post, if you do decide on Botox (I've had it 3x with decent sucess
) , make sure you get a Neurologist or PM who has some experience in performing Botox. In addition to CRPS, I also have Sensory Processing Disorder (and one of my huge SPD areas is tactile defensiveness), allodynia, epilepsy and a few other issues, thanks to good neurologist I was able to handle the Botox process fine (no anesthesia is usually given...painful during the procedure ? yes ... tolerable ? yes and side effects subside within a few days)
Good Luck in whatever you decide !
