A skin abscess is a localized collection of pus in or below the skin. It may begin as a tender, firm lump and later develop a softer center.
Typical features
Pain, warmth, redness, swelling, tenderness, and drainage are common. Fever may or may not occur.
Evaluation
A clinician may diagnose a straightforward skin abscess by examination. Ultrasound can help when the collection is deep or unclear.
Treatment
Incision and drainage is commonly used when pus is trapped. Antibiotics may be added based on severity, surrounding cellulitis, health risks, recurrence, or suspected resistant bacteria.
Do not squeeze
Pressure may force infected material into surrounding tissue or create incomplete drainage.
Frequently asked questions
What is an abscess?
An abscess is a localized pocket of pus that forms in tissue, commonly because the body is responding to infection.
Can I squeeze or cut an abscess myself?
No. Squeezing, puncturing, or cutting it can worsen infection, damage tissue, or spread germs.
Do all abscesses need antibiotics?
No. Treatment depends on location, size, severity, surrounding infection, health risks, and whether drainage is needed.
Do abscesses need drainage?
Many do, especially when pus is trapped. A healthcare professional should decide how and when drainage is performed.
Can a warm compress help?
For some small superficial skin abscesses, a warm moist compress may support natural drainage while you monitor symptoms and seek advice.
Is an abscess contagious?
The abscess itself is not passed like a cold, but bacteria in pus or drainage can spread through contact or shared items.
When is an abscess urgent?
Seek prompt care for fever, rapidly spreading redness, severe pain, facial or eye involvement, immune suppression, or feeling very unwell.
Can an abscess come back?
Yes. Recurrence may reflect persistent bacteria, an underlying cyst, hidradenitis, a fistula, diabetes, or another condition.
How long does healing take?
Healing varies with size, location, treatment, health, and wound care. Follow the clinician’s instructions and attend follow-up.
