A carbuncle is an aggregate of connected furuncles and has several pustular openings. Boils usually resolve by themselves, but severe or recurring cases require medical treatment. Options include lancing and draining the boil, and antibiotics. Symptoms of boils The evolution of a boil includes: A small area of skin becomes inflamed and tender A painful lump appears After a few days, a white or yellow head forms The boil bursts The pus drains out The site heals A scar may form, depending on the severity of the boil.

Risk factors for boils Cuts, abrasions or scratches allow the bacteria to gain access to deeper tissues. Certain factors make a person more susceptible to outbreaks of boils, including: Diabetes — recurring boils may be symptomatic of uncontrolled diabetes, especially for people aged over 40 years.

Poor hygiene — sweat and dead skin cells in natural creases and crevices, such as the armpit, provide a hospitable home for bacteria. Broken skin — other skin conditions, such as eczema, can break the skin surface. Other infections Staphylococcus bacteria can cause a range of infections, from relatively mild to severe and life threatening.

There is a small risk that bacteria may spread from the boil to other areas of the body. Infection can cause inflammation of many organs and tissues, including: Bone osteomyelitis Heart endocarditis Lung pneumonia Meninges, the membranes lining the central nervous system meningitis Skin impetigo Vein septic phlebitis.

Self-help options Suggestions for treating a boil include: Resist the temptation to squeeze the boil. Wash the boil with antiseptic soap. Apply a hot compress for 10 minutes or so, three times daily, to encourage the boil to come to a head.

Cover a burst boil with a bandaid. Wash your hands thoroughly to prevent the spread of infection. Use fresh towels every time you wash and dry the infected areas. Treatment for boils Medical treatment for a severe boil may include antibiotics and lancing.

Boils around the eyes and nose should always be treated by a doctor, because the infection may access the bloodstream and reach the brain. A warm compress or waterproof heating pad placed over a damp towel may also help.

Keep using heat for 3 days after the boil opens. Put a bandage on it so the drainage does not spread. Change the bandage every day. If the boil is draining on its own, let it drain. Keep cleaning it twice a day with soap and water. To help keep the infection from spreading, do not share towels and washcloths with other people. When should you call a doctor? Call your doctor if: The boil is on your face, near your spine, or near your anus.

A carbuncle develops when the infection spreads further beneath the skin to create a cluster of boils. Although most boils and carbuncles don't cause further problems, some people develop a secondary infection. This can range from a minor though often very painful infection of the deeper layer of the skin, such as cellulitis , to rarer and more serious complications, such as sepsis.
