Covering the infected area with a clean, wet washcloth and soaking in a bath containing Epsom salts, baking soda or oatmeal are other treatments that soothe the skin, reports Mayo Clinic.

Swimming outdoors in freshwater lakes and ponds is often the cause of swimmer's itch, although it sometimes occurs after swimming in salt water, explains Mayo Clinic. The itchy rash that looks like reddish pimples or blisters may appear within minutes or days after swimming in infested water. These symptoms occur due to a microscopic parasite that burrows into the skin. With each exposure to the parasite, symptoms often worsen.

Animals, such as waterfowl, are the normal host of the parasite.Learn more about Skin Conditions
