What should you know about pseudomonas aeruginosa folliculitis?

Small red or itchy bumps, pimples or pustules can form around hairs, often after a shared pool, hot tub or other wet environment. The rash may affect areas covered by swimwear, but other sites are possible. It can resemble ordinary folliculitis, acne or ingrown hairs, so the timing and exposure history help. Most cases are limited to the follicles, yet worsening pain, spreading redness or fever changes the level of concern.

Arrange a medical review if the rash is extensive, painful, recurrent or not settling. Shower after swimming, change out of wet clothing, wash swimwear and avoid the suspected water source until it has been checked. Do not pop pustules or share towels, razors or clothing. A clinician may recommend observation, cleansing or prescription treatment; topical antibiotic therapy or oral antibiotics should be used only when appropriate for the diagnosis and severity. Tell them about recent water exposure and medicines that affect immunity.

Seek urgent help if redness spreads quickly, pain becomes severe, swelling is marked, or you develop fever, chills, confusion, faintness or feel very unwell. Prompt review is also appropriate for facial involvement, a large wound, diabetes or reduced immunity. A clinician can check whether the infection has moved beyond the follicles and whether a sample is needed.

Does this fit water-associated folliculitis? Should the bumps be sampled? Which cleanser or treatment is suitable? When can I swim again? What signs would mean the infection is spreading?
