I developed bilateral TN after being infected with Lyme as well. It has been 4 years now. My daughter and I were both infected, and we now both have late stage, chronic Lyme. My LLMD and neurosurgeon both agree that it was Lyme that caused my TN. I can completely understand your statement about believing in Lyme...it's a highly political disease. Every MD claims it's not in their state. Pretty sad.
Anyway, very time I try to take flagyl for my neuro Lyme, I have severe TN attacks that started out lasting hours and now for last days at a time.
I had a balloon compression on my right side which did nothing but to make my pain worse.
From what my LLMD has told me, my TN is not going to "heal itself" as my Lyme symptoms abate. I go through periods of remission, where I feel better, but my TN has continued to get worse since my initial infection of LD, Babesia, and Bartonella in early 2007.
