I am taking 5000mcg VitB12 (Methycobalamine) and R-Lipoic Acid 100mg, among other things.

Oh, I have been into all kind of tests and they all came back negative, even my Skin Biopsy is normal. I was told though, in this forum, that PN, in its early stage comes out normal in the skin biopsy.

I read Mrs.D's recent post about TB medication that could cause PN. I was on TB medication for 9 months in 2000 (or 2001). I also had flu vaccines for the past 3 consecutive years. These two factors are mentioned to be causative of PN. Although I am not sure if these are the real causes of my PN, I am taking supplements for Mitochondrial damage. Anyway, I was already taking the recommended supplements on Mrs.D's Supplements, etc. thread even before I read about the TB meds.

God bless.
