Does anyone know of any signs of nerve healing (axonal regeneration)? I'm trying to be optimistic with my PN thinking that the shooting pains I'm now getting are sort of "hey your nerve is working again and you're healing", but I'm probably just hoping for the best :/

I've been exhausting possibilities since my PN is currently idiopathic and was leaning toward thiamine deficiency causing it. I couldn't find much information about healing from it, and cell death, and asking a doctor in the USA about it yielded no information. Anyways, a few of the questions pertaining to this were: How long does it take during a thiamine deficient state to lose nerve cells, how long until symptoms present till the death of nerve cells, how long would it take to recover, and is it a full recovery? The best information I found stated that recovery was slow, but nothing beyond that.
