Whenever i go in my pool, my nipples get really red and hurt a lot. sometimes i can even see slight bleeding. would this be because of chemicals?

HardToImagine-Maybe: What's in that pool?A mixture of sulfuric acid and blood from that creature in"Alien?"Anything else setting you up for nipple irritation in-between dips in that vat of who-knows-what (like being a test model for a sand blasting machine)?Are you sure it's blood you see? Or just part of the redness?Pools typically have either chlorine or bromine,but there are other chemicals used. Ask your landlord.
