Incision and Drainage of a Skin Abscess
(Skin Abscess, Incision and Drainage)
by Amy Scholten, MPH
Incision (cut) and drainage is a procedure to drain pus from an abscess. A skin abscess ( boil) is a pocket of pus in the skin.
Reasons for Procedure
Drainage of an abscess is the preferred treatment to clear an abscess. It is often used if the abscess is large, growing, painful, or not improving on its own.
Problems are rare, but all procedures have some risk. The doctor will go over problems that could happen, such as:

What to Expect
Prior to Procedure
The doctor may talk to you about:
The doctor will give local anesthesia—the area will be numbed.
Description of Procedure
Most of the time, this procedure can be done in the doctor’s office. Large, deep abscesses, or abscesses in sensitive areas (such as near the anus) may be treated in the hospital.
A small incision will be made. A syringe or catheter may be used to drain the pus from the abscess or the pus may be squeezed out. Gauze may be used to soak up the fluid. A clean water mixture will be used to flush the area.
The doctor may use a tool to look inside the incision. The tool can also help break down the abscess. The doctor may take a sample of bacteria with a cotton swab for testing. Sometimes, the doctor will pack the wound with clean gauze. This will help make sure the abscess does not form again. If this happens, the packing will need to be removed or replaced in 1 to 2 days. Gauze and dressing tape will be used to cover the wound.
How Long Will It Take?
30 to 45 minutes
Will It Hurt?
Some pain in the area is common after the procedure. Medicine and home care help.
The skin should heal in about 14 days. Physical activity may be limited during this time. You will need to clean and replace bandages as instructed. You may need to delay your return to work for a few days.
