In the course of trying to determine for myself the cause of my idiopathic SFN, I've discovered I have glucose issues. There's no way of knowing if they're the cause of it, but one things for sure, my glucose levels spiking to unhealthy levels certainly weren't helping my nerves any.

My symptoms have improved pretty significantly since last year for some reason, but I can't say for sure why. Things I've done: low carb diet, quality Omega 3s, R-Lipoic Acid, benfotiamine, magnesium, milled flax seed.

I'm essentially treating myself as if I'm a diabetic. If any good has come of this, I'll at least hopefully stave off an eventual diagnosis of it.
