I think my last tetanus shot was probably in 1997 when my dog TinyMonsters put his claw thru my eyelid. (I was climbing up the stairs, bent over to pet the dog, he put his foot up and I bumped my face into his toes)

Stupid doctors kept asking me why the dog bit me. Kept telling them he didnt bite me, he had put his foot up and accidentally got me in the eyeball. (the injury was a scratched cornea, and scratch on my eyelid)

They made me get a tetanus shot because I couldnt get anyone to believe me that it wasnt a bite, but a scratch. This was after I had mono in 1996, and just before I can remember my first vertigo attack that I think was my first probable MS attack.
