Allergies

With it being summer and all, I've been on constant alert for 'leaves of three'. My sister and aunt both recently broke out with poison ivy in a couple places, so I've been staying away from them as much as possible. Maybe its not medically possible, but I've always felt that I'm ridiculously allergic to poison ivy (more than most people), simply because of how quickly it travels when I get infected. I'll find a small spot on my leg, cover it so I cant scratch it, and somehow, within a day, it'll be on my face. One summer I had to walk around with gloves on at all times, because both my hands were COVERED with poison ivy. It was not fun.

So while mine may not be considered a true 'allergy', what kind of allergies do other people have? Any interesting stories in how said allergy was discovered?

Jam it back in, in the dark.
