I am having a relapse of my burning sensations in my legs and feet. Somewhat in my hands as well.

I am wondering about the following: I recently dropped L-lysine from my regimen of daily supplements. Could this be the cause of my relapse?

Also, I'd be grateful if someone would remind me of why we are taking L-lysine. My search in on Wikip. didn't tell me much, and my search of this forum only brought me two results, which turned out to be my own earlier posts.

Thanks!
