Thank you for all your replies.

En bloc: I didn’t have any sort of prior period of illness that I’m aware of and hadn’t been taking any antibiotics in the recent past. As far as other AI tests, CRP, RF and Sed Rate were all negative. I don’t have any other systemic signs or symptoms of SLE, RA or other autoimmune processes. The NCS that was done was normal, with some velocities on the low side of normal but still within normal range.

Susanne C: Talking with my mom, she said that one of my aunt’s had some issues with peripheral neuropathy but it started much later in life, in her 60’s.

Jon_Sparky: The Vitamin B12 level taken recently while taking B supplements was ~600.

mrsD: The last vaccine I had before this started was a Tdap about 4 months prior. I had already received my Hep B vaccines when I was younger. I do have an unfortunate history of binge drinking throughout college. I definitely drank too much at times but wasn’t the heaviest drinker I know either (how I justified it). I’m embarrassed to say that these episodes did not cease completely since I’ve entered medical school although they were much fewer and farther between. I brought this up with the neurologist and he didn't think that would be the cause but wanted to get a Thiamine level which was normal. Since the symptoms started, I’ve had a few occasional drinks but it made me so nervous that I might be making the situation worse that I’ve decided to quit drinking completely at this point.

I've been thinking that this definitely could be caused by alcohol since I can't find any other associated factor. It's been something I'm wrestling with a personal level because I feel incredibly dumb and ashamed if my actions brought this on, especially considering my future in medicine. I'm trying to keep hopeful for improvement but after two months I'm worried this is permanent. I've got an amazing wife who has been incredibly supportive throughout this process but I'm worried about wearing her out with my needs.

Thanks to everyone again for responding so quickly.
