You might want to go to a different Dr! Ive already been to see him and he knows absolutely nothing about crps and the only thing he offered me a scs on my very first visit and that was it, many others have also gone to him not realizing that he wasn't any good and were highly disappointed aswell. I am going to make an appt with Dr Chen in DC at GW hospital as she does specialize in CRPS and does ketamine treatments.
