He currently takes additional B12 (the good kind!) and his levels are good - in fact they always have been. I'm not sure if his B6 was ever tested.

He has idiopathic small and large fibre PN affecting feet and hands.

His pain levels have increased dramatically within the last year (he's had this for about 8 years now), and along with a medication change, his doctor has now suggested the B1/B6/B Complex.

Maybe we'll just try the benfotiamine and go from there.

Thanks again, Linda
