Anterior abdominal wall cellulitis: what to do

It commonly presents with an enlarging area of redness, warmth, swelling and tenderness. Fever or feeling unwell can occur. Because other abdominal-wall problems can resemble cellulitis, a clinician should examine the area and look for a wound, abscess or deeper source.

Bacteria can enter through a small break such as a scratch, cracked skin, an injection site, a surgical wound or irritation within a skin fold. Sometimes the entry point is too small to see. Cellulitis spreads through skin and underlying soft tissue rather than staying as a surface rash.

The examination considers the size and progression of redness, pain, drainage, skin colour, vital signs and possible pus beneath the skin. Recent abdominal surgery, injections, wounds, immune-suppressing treatment, diabetes and previous skin infections help the clinician judge whether additional testing or hospital care may be needed.

Arrange prompt clinical assessment rather than relying on creams or home remedies. Antibiotics are commonly required, while a collection of pus may need a procedure because medicine alone may not empty it. Keep the skin clean and dry, and avoid squeezing, puncturing or massaging a painful swelling.

Take prescribed medicine exactly as directed. You can note or photograph the visible edge, without delaying care, to help track whether it visibly expands. Attend the planned review and seek earlier reassessment if pain, redness or systemic symptoms worsen, or if treatment is not producing the expected change.

Seek urgent care for rapidly spreading redness, severe pain, blistering, dusky or numb skin, pus, wound separation, fever, repeated vomiting or increasing abdominal tenderness. Recent abdominal surgery or a rapidly changing wound lowers the threshold for immediate surgical review.

Call emergency services if there is confusion, faintness, unusual drowsiness, difficulty breathing, very fast breathing, cold or mottled skin, or very little urine. Sepsis can present with these features, which should not be watched at home.

Ask whether there is an abscess, wound problem or deeper infection; whether any scan, sample or drainage is needed; how and when the affected area should be reviewed; which wound-care products are suitable; and what exact symptoms mean you should return urgently.
