What should you know about pseudomonas aeruginosa cellulitis?

Pseudomonas aeruginosa can enter through broken or water-exposed skin, a wound, burn or procedure site. Cellulitis may produce expanding redness, warmth, swelling and painful skin. The organism cannot be identified reliably from appearance alone, so clinicians consider the setting, wound features and overall health; a swab or other sample may be useful when drainage or a wound is present. Diabetes, immune suppression and poor circulation can make skin infections harder to manage.

Seek prompt medical assessment for suspected cellulitis, particularly after a wound or water exposure. Keep any wound covered with a clean dressing, wash your hands before and after touching it, and avoid swimming or sharing towels until assessed. Take prescribed antibiotics exactly as directed; treatment may need adjustment when test results identify the organism. Do not use leftover antibiotics or squeeze a wound. Mention recent hospital care, surgery, burns, hot-tub exposure and medicines that affect immunity.

Go to urgent care for rapidly spreading redness, severe or escalating pain, marked swelling, fever, chills, confusion, faintness, breathing difficulty or a sudden decline. These can indicate a deeper infection or sepsis. Seek earlier review if the infection involves the face, hand or a wound, or if you have diabetes or reduced immunity. Painful skin, skin redness and skin swelling are useful details to report.

Could this be cellulitis or another wound infection? Should a sample be tested? Does my recent water exposure change treatment? How should I dress and clean the area? What response should I expect, and when should I return if it is not improving?
