Sandra, the term bells palsy is just a "fancy" term for facial paralysis.. It can either be chronic (due to a multitude of causes: recurrent tumors along the path of the nerve, meningitis, stroke, DM, chronic infectins... etc) or acute due to actual trauma of the facial nerve like I had mentioned and i see most often than not in the OR. I didnt really read the entire post (I tend to do that on these boards)...
However, it is true that both lyme disease and herpes zoster virus can also cause Bells Palsy, a simple blood panel can show lyme-specific antibodies/ HSV and i assume that is what Vinny had done.
Keep in mind, various illness dont always have to have 1 cause, but in the case of Vin's condition, assuming he has caught the Lyme disease early, he should make a full recovery... and Id highly doubt any other factors (IGF-1 use etc) have any role in this..
