Your B12 was in a good place. You shouldn't have stopped it.

Your B6 is not high either...since the ranges are for people not taking anything. One has to take grams of B6 for long periods of time before any nerve damage occurs. You could get by with your B6 dose 2 or 3 times a week instead of every day if that bothers you.

You really need to read up. That is the only way.

Your burning may be viral...or infectious in some way.

I edited my post you quoted, to give Dr. Latov's reference.
He is in NYC and maybe you should see him.

You are allowing yourself to get upset too much over this. By stressing yourself, you put yourself into high cortisol levels and fuel inflammatory processes. This is a real flare for PNers... all of us understand stress and flare.

Go see a PN specialist and exhaust those tests you did not have yet. There might be answers there for you.
