I had severe eye problems that set in within about six months of diagnosis. I was convinced that my vision problems could be addressed by new glasses but after a visit to the eye doctor I was told that that new glasses would not help. Both my neuro and PM docs agreed the symptoms were CRPS related. The problems only became worse as did my other symptoms until I was treated with tDCS. My improvements were slight during the first course of treatment. Now that I am treating on a regular basis I have seen dramatic improvements in my vision, including elimination of dry eyes.
