Skin abscess (collection of pus)
About Skin abscess (collection of pus)
A collection of infected material just under the skin. The body walls off the infection, which traps the infected fluid. If untreated, the abscess can slowly grow or spontaneously erupt through the skin, leaking purulent fluid. Occasionally the infection can enter the blood stream and cause a life threatening illness. The disorder is usually secondary to a bacterial infection and is frequently caused by a staphylococcal bacteria.Symptoms
Pain, swelling, redness, tenderness, increased warmth of the skin overlying the abscess, hardened skin over the abscess.Tests & Diagnostics
A history and physical exam will be performed. This is diagnosed without additional tests. A culture of the infected material may be done.Prescription medications
Conventional treatment summary
Some abscess can be treated with warm moist compresses. Most require incision and drainage of the abscess. If there is significant redness around the abscess (cellulitis) an antibiotic may be given. Methicillin resistant staphylococcus (MRSA) is becoming more prevalent and an antibiotic effective against this bacteria may be chosen.Medical specialties
