How To Get A Boil To Go Away

Boils

Furuncle

A boil is an infection that affects groups of hair follicles and nearby skin tissue.

Related conditions include folliculitis, an inflammation of one or more hair follicles, and carbunculosis, a skin infection that often involves a group of hair follicles.

Causes

Boils are very common. They are most often caused by the bacteria Staphylococcus aureus. They can also be caused by other types of bacteria or fungi found on the skin's surface. Damage to the hair follicle allows the infection to grow deeper into the follicle and the tissues under it.

Boils may occur in the hair follicles anywhere on the body. They are most common on the face, neck, armpit, buttocks, and thighs. You may have one or many boils. The condition may occur only once or it can be a long-lasting (chronic) problem.

Symptoms

A boil may begin as tender, pinkish-red, and swollen, on a firm area of the skin. Over time, it will feel like a water-filled balloon or cyst.

Pain gets worse as it fills with pus and dead tissue. Pain lessens when the boil drains. A boil may drain on its own. More often, the boil needs to be opened to drain.

The main symptoms of a boil include:

A bump about the size of a pea, but may be as large as a golf ball
White or yellow center (pustules)
Spread to other skin areas or joining with other boils
Quick growth
Weeping, oozing, or crusting

Other symptoms may include:

Fatigue
Fever
General ill-feeling
Itching before the boil develops
Skin redness around the boil

Exams and Tests

The health care provider can usually diagnose a boil based on how it looks. A sample of cells from the boil may be sent to the lab for a culture to look for staphylococcus or other bacteria.

Treatment

Boils may heal on their own after a period of itching and mild pain. More often, they become more painful as pus builds up.

Boils usually need to open and drain in order to heal. This most often happens within 2 weeks. You should:

Put warm, moist, compresses on the boil several times a day to speed draining and healing.
Never squeeze a boil or try to cut it open at home. This can spread the infection.
Continue to put warm, wet, compresses on the area after the boil opens.

You may need to have surgery to drain deep or large boils. Get treatment from your provider if:

You have a fever or other symptoms with the boil.
The boil causes pain or discomfort.
You have a boil on your spine or the middle of your face.
A boil lasts longer than 1 week.
A boil comes back.

It is important to keep a boil clean. To do this:

Clean boils and change their dressing often.
Wash your hands well before and after touching a boil.
DO NOT reuse or share washcloths or towels. Wash clothing, washcloths, towels, and sheets or other items that have touched infected areas in hot water.
Throw out used dressings in a sealed bag so that fluid from the boil does not touch anything else.

Your provider may give you antibiotics to take by mouth or a shot, if the boil is very bad or comes back.

Antibacterial soaps and creams cannot help much once a boil has formed.

Outlook (Prognosis)

Some people have repeated boil infections and are unable to prevent them.

Boils in areas such as the ear canal or nose can be very painful.

Boils that form close together may expand and join, causing a condition called carbunculosis.

Possible Complications

These complications may occur:

Abscess of the skin, spinal cord, brain, kidneys, or other organ
Brain infection
Heart infection
Bone infection
Infection of the blood or tissues (sepsis)
Spinal cord infection
Spread of infection to other parts of the body or skin surfaces
Permanent scarring

When to Contact a Medical Professional

Call your provider if boils:

Appear on your face or spine
Occur along with a fever, red streaks coming out from the sore, a large build-up of fluid in the area, or other symptoms of infection
Cause pain or discomfort
Do not heal with home treatment within 1 week
Come back after treatment

Prevention

The following may help prevent the spread of infection:

Antibacterial soaps
Antiseptic (germ-killing) washes
Keeping clean (such as thorough hand washing)
