I do deal with sensitivity also. As far as shots, my Dr. uses zylocaine for my RSD, Fibro, TOS, and Costo. They work but it takes a series of them to calm things down. I was also given zylocaine to put in my bladder for the IC.

I finally got my feet warmed up and then I went to town Sat. and was on my feet for too long and started the cold and burning in them again. It feels like my feet were frostbitten. My legs are hurting also.
