Flagyl either aggravated or caused my PN. I haven't taken it for over 5 years, but I did take it on and off over the course of a year in 2002-03.

I will be trying the niacin therapy, along with my methylcobalamin B12. It is getting to the point where I get no sleep, between the feet and hands, the gall bladder (upcoming surgery) and the Crohn's and the tinnitus.

I hope that yours is only temporary and dissipates soon.
