I hate alergies but i have them :(?

i love swimming. i go to the beach everyday and we have a pool. but the problem is im allergic to chlorine. i get hives. so we have to use a saltwater filter... which is a pain... but recently it has gotten worse. now sometimes i just wash my hands and my legs and hands get splotchy red and so do my legs and they itch!! A LOT!! D: do you guys think there are any things i can do before i have to get an allergy test or something? i dont want to be allergic to chlorine for the rest of my life. when i was younger and my friends and i would have water fights or play with a slip n' slide i thought it was normal to get really itchy. i really dont think that should happen though. BUT its only on my external skin it doesnt happen when i drink tap water or anything. i say tap water though because tap has higher levels of chlorine. so again, what should i do before i have to have an allergy test?
