Alcoholic neuropathy is just one of the problems related to Alcohol abuse, as Jacker suggested it is best to get a Doctors opinion.
Alcoholics can have many physical symptoms, but there's nothing to say whether this is caused (or not caused) by the alcohol abuse. I used to get a quick cramp in my thigh when I was drinking and I have to say that I haven't had them since I stopped. Still, it could have been caused by almost anything. A Doctor's opinion would be your best bet.
