The most common cause of furuncles is theStaphylococcus aureus(staph) bacteria, but other types of bacteria or fungi on the surface of the skin can also cause them. The infection grows into a hair follicle and the tissues under it.

Furuncles can go away on their own, but getting medical treatment is often a good idea to help relieve pain, prevent complications, and promote quicker healing.

What a Furuncle Looks Like

A boil can start as a swollen, tender, inflamed, pinkish-red area of the skin and then become a painful bump. The bump can feel like acystor water-filled balloon, filling with pus and dead tissue.

The boil is centered on a hair follicle.

How to Get Rid of a Boil at Home Safely

When the boil first appears and the pus-filled space hasn’t fully developed, applying a warm, moist compress can help bring the pus to the surface. This technique can help speed up the development of the abscess so that it can drain and heal.

Possible Complications From Furuncles

Carbuncles

Spreading Infection

Infection can spread to other body areas, particularly if you squeeze or scratch it open. The bacteria can spread along the blood or lymph vessels. Red streaks leading away from the boil indicatelymphangitis(infection moving along a lymph vessel).Lymphadenitis(inflammation and pain in the lymph nodes in the affected area) can also occur.

A boil on the face (especially around the nose or upper lip area) carries a risk of bacteria entering the brain, which could lead tomeningitisorcerebral venous sinus thrombosis(life-threatening blood clots in the large blood vessels).

Cellulitis(infection of the surrounding tissues) can also cause fever and illness.

Sepsis

Sepsis (the body’s extreme response to an infection) occurs when an infection triggers a life-threatening chain reaction throughout the body. Sepsis is a medical emergency.

Symptoms of sepsismay include:

MRSA

Methicillin-resistantStaphylococcus aureus(MRSA)is a type of staph bacteria that can be resistant to certain antibiotics.An MRSA infection can cause boils.

Antibiotics taken for boils due to MRSA infection need to be a type that is effective against MRSA bacteria.

What Causes a Furuncle?

About 10% to 20% of people arestaphylococcalcarriers (they carry the bacteriaStaphylococcus aureuson the surface of their skin), even if they are otherwise healthy and have good hygiene. This bacteria is commonly carried in the nostrils, between the legs, in the armpits, and in the cleft between thebuttocks. It can move from the nostrils to other areas via fingernails.

Bacteria can enter the wall of a hair follicle andcause an infectionin the follicle and surrounding tissue. The infection causes skin tissue inside the boil to die, creating anabscess(a pus-filled hollow space).

Factors that may increase the risk of developing a boil include:
