Hi, I am new so please bear with me, I was shocked to actually read that someone else's RSD itches like mine..at least I know I'm not losing it...so far I only have the RSD rash on my right foot and half way up my leg but my knees have the pain along with my foot and leg...I have heard this can spread to your whole body but did it start like in your foot and spread?? I've only been diagnosed for about 6 months so I hope I don't sound dumb but I really have a lot of questions because my doctors don't really know that much about it and I can't find one that does. Thanks for making me feel welcome...
