Hi Alt,

I get that exact same rash on both my legs especially after sun exposure. My doctor calls it a neurogenic rash. We know it is for sure CRPS related since in my legs the CRPS is only on the front and slightly to the sides but not the back and the rash is only in that area. On my arms the rash does not seem to appear but that area is not nearly as severe as my legs. I also have small red dots on the skin of legs that never goes away and seems to precipitate spread. My legs burn constantly so I'm not sure I couldn't tell you if the rash makes the burn worse or not. I do know it increases pain and electrical shocks when it is starting to appear. Were you perhaps in the sun? It also doesn't matter if I have clothing over the skin when the rays hit.. even through the windshield of my car it still happens every time. Curious to know if yours is also triggered by sun exposure?
