I was diagnosed last week with PN based on symptoms and a nerve test. It has come on suddenly although I have had slight numbness in my feet for over ten years. I think the combination of a daily dose of Protonix and Metformin* caused a b12 deficiency ... and now with what I've read here ... I'm pretty sure that's the cause. I'm not diabetic and I WAS very fit, so I'm hoping that I can restore my B12 levels and stop the progression of nerve damage.

Of course, 3 out of 3 doctors agree that my "normal" B12 serum level precludes a B12 deficiency as the cause of my symptoms. They also all agree that there's nothing they can do.

BUT ... armed with the information that each of you so generously shared ... I'm going to the 24-hour Walgreens to buy a bottle of Methyl B12 (and will take on an empty stomach!).

Any advice on B12 brands or issues I need to know will be gratefully appreciated! Also - are shots better? My situation is pretty bad ... significant impaired gait, twitching and jumping muscles in legs and arms and feet are totally "gone".
