I know a guy who had Bell’s Palsy... He was an ambulance driver and he knew he had it... Went to the emergency room and he needed to convince them that he wasn’t having a stroke. That’s what the doctor’s and nurses thought. It’s typically temporary and it was for him, but some people’s facial muscles never recover. They’re fine, they just look screwed up.
Curtis Lemay had Bell’s Palsey, which affected the left side of his face, and which he generally tried to mask by chomping on a cigar.
