I have had alot more cramping in my calf muscles & general subjective twitcing,flinching & what feels like exagerated startles.

I have small fibre pn. I am a bit concerned, as my left leg has caused me alot of problems. I have no weakness.

Is all this still just part of having SF PN? Are these common symptoms? I have had SF for the last 20 months, and only in the last 3-4 months have I had crazy pulsating vibration feelings, and twitching and spasming.

Thanks guys-
