Just a quick update of my treatment with tDCS. I recently had a very minor sinus infection that did not require antibiotics. To my surprise my CRPS symptoms returned with a vengeance. The return of a stiff claw hand was very scary. After having a brief pity party I surmised that my illness, however slight, ignited an inflammatory response that snapped the CRPS to attention, much like spreads of CRPS ignited by surgical procedures.

I am assuming that I was correct because soon after the illness resolved the CRPS flare subsided.

Hope this is helpful to someone!
