Definition
A boil is a red, swollen, painful bump under the skin that is caused by an infection. Boils often start in an infected hair follicle. Bacteria form an abscess or pocket of pus. Eventually, the pus may come to a head and drain out through the skin. Boils can occur anywhere, but common sites include the face, neck, armpits, buttocks, groin, and thighs.
There are several types of boils:
- Furuncle or carbunclean abscess caused by the bacteria Staphylococcus aureus or Streptococcus pyogenes . This type sometimes occurs as several boils in a group.
- Pilonidal cystan abscess that occurs in the crease of the buttocks. These almost always require medical intervention.
- Cystic acnean abscess that occurs when oil ducts become clogged and infected. This is more common in the teenage years.
- Hidradenitis suppurativaan uncommon disorder where multiple abscesses occur in the armpit and groin area

DiabetesPoor nutritionPoor hygieneWeakened immune systemExposure to harsh chemicals Symptoms Symptoms may include: Skin lump or bump that is red, swollen, and tenderLump becomes larger, more painful, and softer over timePocket of pus may form on top of the boil (This is called "coming to a head.") DiagnosisThe doctor will ask about your symptoms and medical history, and perform a physical exam. A bacterial culture of the boil may be taken. Some boils do not require medical attention and may drain on their own. More serious symptoms associated with boils that may require medical attention include: The boil worsens, persists, or becomes large or severe.You have a fever.The skin around the boil turns red or red streaks appear.The boil does not drain.An additional boil or boils appear.The boil limits your normal activities.The boil is on your face, near your spine, or in the anal area.You have diabetes.You develop many boils over several months. TreatmentYour doctor can drain the boil if necessary and treat the infection with antibiotics.Home treatment may include: Warm CompressesApply warm compresses to the boil for 20 minutes, 3 to 4 times a day. Depending on the area of the body affected, you may be able to soak the boil in warm water. These measures can ease the pain and help bring the pus to the surface. Once the boil comes to a head, repeated soakings will help the boil begin to drain.
Lancing the BoilDo not pop or lance the boil yourself. This can spread the infection and make it worse. If the boil does not drain on its own or it is very large, you may need to have it drained or lanced by your doctor. Cleaning and BandagingWhether the boil drains on its own or was lanced by a doctor, you must keep it clean. Wash it with antibacterial soap and apply a medicated ointment and bandage. Clean the affected area 2 to 3 times a day until the wound heals completely. Prevention To help prevent boils: Practice good hygiene. Wash boil-prone areas with soap and water or an antibacterial soap. Dry thoroughly.Clean and treat any minor skin wounds.Avoid clothing that is too tight.
