Folliculitis after swimming in a pool

An itchy or tender crop of red bumps may appear under a swimsuit or on areas covered by wet fabric. Pool-associated folliculitis is different from simple chlorine irritation, although both can cause redness. The timing, distribution, and whether bumps contain pus help a clinician assess the cause. Ingrown Hairs or other Skin Bumps may look alike, so do not assume every post-swim rash is an infection.

Remove wet swimwear promptly, rinse the skin with clean water, and wash gently before drying thoroughly. Launder the swimsuit and avoid sharing towels or razors. Keep irritated skin cool and avoid scratching, shaving, or squeezing bumps. Do not apply antibiotics without advice. If the eruption persists or is spreading, a clinician can decide whether Topical Antibiotic Therapy or another treatment is suitable.

Arrange an examination if redness expands, pain increases, bumps become large or pus-filled, or you develop fever or feel unwell. Seek advice sooner if several people who used the same pool develop a similar rash, or if you have a condition or medicine that affects immune function. Antibiotics For Skin Infection may be needed in selected cases, but treatment depends on the findings.

Ask whether the rash resembles Folliculitis or chlorine irritation, whether you should avoid the pool temporarily, and how to clean or treat the skin. Share when you swam, how long the swimsuit stayed wet, and whether the bumps itch, hurt, or drain.
