Insect Sting Allergies

I'm allergic to bees and I know that because I've been stung and when I get stung, I swell up really bad. I'm not about to go into anaphylactic shock or anything like that. Luckily, I haven't been stung anywhere up here or otherwise I might. But whenever I get stung, I swell up really bad. One time I stepped on a bee, my foot swelled up so bad I couldn't walk on it for like almost two weeks and the swelling took a long time to go back down. It just looked like one of those latex gloves when you blow them up and like the palm is super puffy and then like the fingers are just like fat, but it's just that, you know, that shape that I'm talking about. That's what my foot looked like.
