When I was about 10 I ripped my knee open on piece of rusty metal. I had to have about 10 stitches and at the time they did a test to determine if I was allergic to tetnus. I had a violent reaction to the test so they told me to never get any shots that have an egg serum base. It turns out just about all shots are egg based. I spent 6 years in the Navy traveling the world and escaped getting any of the normal shots required for foreign travel. In fact I recieved no shots while in the Navy.

I found I was allergic to Novolcane at about 7 so I had to have all dental work done without any deadening. That was back in the day of the old slow drill too. Today my dentist uses lidocaine that I tolerate well.

I have found as a adult that I am very allergic to Augmentin antibiotic. I spent several days in the Hospital after Augmentin treatment. It caused "C diff" which is something you don't wish on your worst enemy.
