Com. You develop reddened and irritated skin, sometimes with raised red bumps on your skin. Swimmer's itch is another skin condition that causes red and raised bumps or even blisters on your skin. Parasites in infected water cause swimmer's itch. The condition usually resolves itself after about one week.
