Yes my first brain scan with contrast was in 2005, right after a deer tick bite. I had neurological symptoms a month or two after that bite. One negative Lyme test later, my PCP jumps to the conclusion that I might have MS. If I could go back in a time capsule to yell "Occam's Razor", tell her per the CDC that Lyme is a clinical diagnosis, and fire her, I would. Back then, I had too much faith in medicine and doctors.
