What am I alergic to in the pool?

Factual Questions
1

I started swimming again a few weeks ago and every time I get out of the pool I spend the rest of the day with a stuffy, runny nose, often with sneezing, puffy, itchy, eyes and often swollen face.

This is a community pool and generally no one else I know has any issues there.

2

Could it just be spending that time outside that you might not normally spend exposed to pollen and such? Just an idea.

You may be allergic to the pool chemicals.
