I have RSD in both feet, it came on in both at the same time altho the left foot is the worst & it started in 2003 but not DX'ed until 2004.

And also after some types of treatments such as Stellate Ganglion Nerve Blocks whether SGB's or LSB's depending on what extremities are affected, the symptoms can change. I stopped getting the sensitivity from say wind on my skin altho cloth brushing me drove me nuts. But now 4 to 5 yrs down the road & after many nerve blocks I can now wear socks, altho they have to be chenille. I can't wear any other type of cloth on my feet. I can also stand to wear slippers & shoes now also. I can stand to have blankets touch/brush my feet now too. I also no longer get the shiney swollen look. They still will show bright red when on fire so to speak. They do not look blue to purple now either. So over time you might loose some symptoms while getting new ones.

My 2 cents for what it is worth *LOL*
