I know this is a long shot but here it goes. I began taking NAC 3 weeks before the burning in both my feet started. I was having some pain in my left foot a month before taking the NAC which wasn't obvious nerve pain at the time.

I haven't found anything online which would indicate it. As a matter of fact everything about NAC claims to help nerve pain. Regardless I stopped taking it immediately after the onset of burning pain in both feet just to be safe.

Just trying to think of the changes in the weeks/months leading up to my recent symptoms. Could NAC have anything to do with agitating the peripheral nerves??
