I also tried Amantadine, but couldn't stick with it long enough to see if it helped any as it made me dizzy/lightheaded and that didn't bode well with my anxiety. I am currently trying the amino acid supplement Carnitine as it doesn't affect the central nervous system. My tingling hasn't been bad enough to really bother me so I haven't taken anything for it yet.
Bonnie, so sorry to hear about your flare! I am in one too from the waist down, looks like it is from a bladder infection. I hope you feel better really soon.. pain stinks!!
