My pricklies pre-dated my SFN by a few years. I think they're some kind of a response to physical discomfort. I'm pretty sure I experienced them when I gastritis really bad in 2010 and then shingles in 2011. I wish I knew for sure that they didn't start with shingles, but I just can't remember. All I know for sure now is that they're a "pile on" feature. I never have them when my other symptoms aren't bad, and they're never stand-alone.

Patrick, do you have lidocaine patches for your feet? I find they really do help.
