I have had a slow progression of numbness and then tingling in my feet for a few months. My general doc who I just saw for a checkup said it was PN with alcohol or idiosyncratic casuses. My B-12 was around 400. I haven't gotten into see a neurologist yet but have stopped drinking and started on the suggested B12 & other Bs program. I'm starting to already feel less numbness and the tingling has moved down my leg to mostly my feet. I spend a lot of time outdoors and have had many tick bites so I'll have my neurologist check for lymes too. I've had one or two glasses of wine in the last few weeks but not the usual 2 to 3 most days. I hope the improvement continues! Thanks to everyone who has contributed to this site!
