Anyone ever had an allergic reaction after swimming?

The last two times I went this week, I began sneezing and had itchy watery eyes and nose for about 16 hours after. The first time I thought I was getting a cold but it disappeared the next day. The second time I made the connection to the pool. I called the YMCA to see if they'd changed chemicals or anything and they admitted they were having some trouble with the chlorine dispenser. This last bout was enough to make me think twice about going back but I have to. I may call first before I go. Hope it's not a lasting thing. Has it happened to anyone else??
