<unk>  or hot-tub rash is an infection of the skin. The skin may become itchy and progress to a bumpy red rash that may become tender. There may also be pus-filled blisters that are usually found surrounding hair follicles. Because a swimsuit can keep contaminated water in longer contact with the skin, the rash may be worse under a person’s swimsuit.
