Treatment
Small boils can be treated with moist heat (usually a warm, wet washcloth) applied for 20 to 30 minutes, three or four times a day. This will help the boil drain on its own. Once the boil drains, cover it with a clean bandage to protect the skin and absorb draining pus. Wash the affected area daily with antibacterial soap to prevent the infection from spreading. Anyone who helps care for the infected area should also wash his or her hands thoroughly with antibacterial soap.
Large boils may be treated with antibiotics. In many cases, the doctor will drain the infected area through a small incision. This will relieve pain, speed recovery and limit scar formation. If the infection is completely drained, antibiotics may not be necessary. If the infection is deep, your doctor may cover it with a piece of sterile gauze to keep the incision open and allow pus to continue to drain. You may need to return to the doctor a few times to have the gauze and dressing changed and to make sure the infection drains completely.
When To Call A Professional
Call your doctor whenever you have a carbuncle, a large boil or a boil that doesn't improve after a week of home treatment as described above. If you have diabetes, you should call your doctor even if you develop a small boil because you are more prone to developing serious infections. Ask to be seen immediately if a boil of any size:
* Develops in an infant
* Is located on the face, rectum, groin or spine
* Produces fever or severe pain
* Interferes with movement of a body part
* Causes swelling, red streaks or other discoloration in nearby skin
If you have had several episodes of boils within a short period of time, visit your doctor. Your doctor can check whether an undiagnosed medical illness is affecting your body's ability to fight infections.
Prognosis
Most small boils heal without leaving a scar. In general, the larger the boil or carbuncle, the greater the chance that it will leave a scar. Because of this, you should see a doctor if you have a boil on your face. Antibiotic treatment and surgical drainage can help limit scar formation.
