Boils or skin abscesses are large, sore, reddish bumps resulting from infections deep in the skin. A carbuncle, a type of skin infection, is a mass under the skin formed by a group of boils.
A boil is a painful lump filled with pus that grows until it ruptures and the pus drains. A boil usually starts as a tender area that becomes hardened and swells resembling a "blind pimple." Usually, a carbuncle, which is contagious, occurs when a bacterial infection inflames hair follicles. When a person has more than one of these, he has carbunculosis. It can develop slowly but eventually the center will soften and develop a "head." The head is filled with bacteria, proteins, and the accumulation of white blood cells sent to fight the infection, otherwise known as pus. When the boil reaches its final stage, it can be drained by lancing or it may spontaneously drain. Applied hot packs will help this process along, as the heat draws more blood to fight the infection.
The bacterial infection that usually causes a carbuncle is caused by the staph bacteria, also known as staphylococcus aureus. The bacteria make its way into the affected person through a cut or scratch and infect the hair follicle, which then causes the skin infection to develop. As the body fights the infection, inflammation occurs, and the result is the formation of pus, which is a combination of bacteria, dead skin cells and white blood cells. People who are most susceptible to a staph infection are those with certain conditions such as dermatitis and diabetes.
In comparison to a single boil, a carbuncle is a deeper, more severe condition that develops and heals at a slower rate. The main symptom of this condition is the mass itself, which can vary in size from being as small as a pea to as large as a golf ball. Pus oozes out of the center, which might be yellow or white in color. In addition, the mass might hurt and be irritated. Other symptoms that can accompany the mass are chills, fatigue and fever, as well as itchy skin prior to the development of the mass.
A boil is a localized infection in the skin that generally starts as a reddened, tender area. Over time, the area becomes firm, hard, and tender. Eventually, the center of the boil softens and becomes filled with infection-fighting white blood cells from the bloodstream to eradicate the infection. This collection of white blood cells, bacteria, and proteins is known as pus. Finally, the pus "forms a head," which can be surgically opened or spontaneously drain out through the surface of the skin. Pus enclosed within tissue is referred to as an abscess. A boil is also referred to as a skin abscess.
There are several different types of boils:
Furuncle or carbuncle: This is an abscess in the skin usually caused by the bacterium Staphylococcus aureus. A furuncle can have one or more openings onto the skin and may be associated with a fever or chills. The term furuncle is used to refer to a typical boil that occurs within a hair follicle. The term carbuncle is typically used to represent a larger abscess that involves a group of hair follicles. A carbuncle can form a hardened lump that can be felt in the skin. The condition of having chronic, recurring boils is referred to as furunculosis or carbunculosis.
Cystic acne: This is a type of abscess that is formed when oil ducts become clogged and infected. Cystic acne affects deeper skin tissue than the more superficial inflammation from common acne. Cystic acne is most common on the face and typically occurs in the teenage years.
Hidradenitis suppurativa: This is a condition in which there are multiple abscesses that form under the armpits and often in the groin area. These areas are a result of local inflammation of the sweat glands. This form of skin infection is difficult to treat with antibiotics alone and typically requires a surgical procedure to remove the involved sweat glands in order to stop the skin inflammation.
Pilonidal cyst: This is a unique kind of abscess that occurs in the crease of the buttocks. Pilonidal cysts often begin as tiny areas of infection in the base of the area of skin from which hair grows (the hair follicle). With irritation from direct pressure, over time the inflamed area enlarges to become a firm, painful, and tender nodule that makes it difficult to sit without discomfort. These frequently form after long trips that involve prolonged sitting.
Boils can occur anywhere on your skin, but appear mainly on your face, neck, armpits, buttocks or thighs — hair-bearing areas where you're most likely to sweat or experience friction. Signs and symptoms of a boil usually include:
A painful, red bump that starts out about the size of a pea
Red, swollen skin around the bump
An increase in the size of the bump over a few days as it fills with pus (can sometimes reach the size of a golf ball)
Development of a yellow-white tip that eventually ruptures and allows the pus to drain out.
Boils can be single or develop in clusters. When a boil first forms, it will appear as a swollen, painful red lump that's similar in size to a twenty pence piece. Over the next few days, the boil will begin to grow.
The size of boils can vary significantly. Some boils can grow to the size of a golf ball. Yellowish-white colored pus will begin to build up at the center or tip of the boil. However, it's very important to resist the urge to squeeze the boil because it could lead to more serious complications.
Eventually, the boil will usually burst open and the pus will drain away, leaving your skin to heal. This can take from two days to three weeks to happen. Most boils don't leave any scarring unless they're particularly large.
Once the boil drains, the pain usually subsides. Small boils usually heal without scarring, but a large boil may leave a scar.
A carbuncle is a red, hard painful lump that grows over the space of a few days. It usually develops on the back of the neck, the back or thighs. Carbuncles:
cause a deeper and more severe infection than single boils do
develop and heal more slowly than single boils do
are likely to leave a scar
A fully grown carbuncle can range in size from 3cm (1.1 inches) to over 10cm (4 inches), and will leak pus from a number of points. You may also have additional symptoms, such as:
a high temperature of 38ºC (100.4ºF) or above
a general feeling of being unwell and 'out of sorts'
feeling weak and exhausted
When to seek medical advice
You usually can care for a single, small boil yourself. But see your doctor if you have:
a moderate to large boil that feels soft and spongy to the touch
a boil or carbuncle that worsens rapidly or is extremely painful
a boil on your face or spine – this can sometimes cause serious complications
additional symptoms, such as a high temperature or feeling generally unwell
a secondary infection, such as cellulitis (an infection of the deeper layer of the skin)
a boil and a health condition that is known to weaken the immune system, such as an organ transplant, type 2 diabetes, corticosteroid use or HIV or AIDS
a boil and you're receiving medical treatment that's known to weaken the immune system, such as chemotherapy
a boil that shows no sign of healing after two weeks
recently been hospitalized
Children and older adults who develop one or more boils also should receive medical care.
Boils usually form when one or more hair follicles — the tube-shaped shafts from which hair grows — become infected with staph bacteria (Staphylococcus aureus). These bacteria, which normally inhabit your skin and sometimes your throat and nasal passages, are responsible for a number of serious diseases, including pneumonia and endocarditis — an infection of the lining of your heart. They're also a major cause of hospital-acquired infections.
Staph bacteria that cause boils generally enter through a cut, scratch or other break in your skin. As soon as this occurs, specialized white blood cells called neutrophils rush to the site to fight the infection. This leads to inflammation and eventually to the formation of pus — a mixture of old white blood cells, bacteria and dead skin cells.
Who's at risk
Known risk factors (things that make you more likely to get boils) include:
being male (particularly a teenage boy) – this could be because the hormonal changes during puberty can make the skin greasy, which may encourage the growth of bacteria
being in close personal contact with someone who has a boil – you're more likely to develop an infection if you live with someone who has a boil or carbuncle.
diabetes – this disease can make it more difficult for your body to fight infection, including bacterial infections of your skin.
taking part in sports that involve a combination of close personal contact and frequent friction to the skin, such as rugby and wrestling
living in conditions that are overcrowded and/or have poor standards of personal hygiene
having a pre-existing skin condition, such as atopic eczema, acne or scabies, make you more susceptible to boils and carbuncles
obesity – being very overweight with a body mass index (BMI) of 30 or above
compromised immunity – if your immune system is compromised for any reason, you're more susceptible to boils and carbuncles
Like boils, carbuncles are also caused by staphylococcus aureus bacteria. A carbuncle develops when the infection that causes a single boil spreads beneath the skin to create a cluster of boils.
People who are in poor health or those with a very weak immune system (the body's natural defense against infection and illness) are thought to be most at risk of developing a carbuncle. These include people:
with diabetes – high sugar levels in the blood make it more difficult for your immune system to protect you against skin infection
with health conditions known to weaken the immune system, such as HIV
who are on a long-term course of steroid tablets or injections (corticosteroids) – long-term steroid use makes you more vulnerable to infection
who are having treatment known to weaken the immune system, such as chemotherapy
who are malnourished (not getting the nutrients needed from food to maintain good health)
with skin conditions that affect a large part of their body, such as more severe forms of psoriasis
with heart failure
with a severe drug misuse problem, particularly those who inject drugs
In most cases, boils can be treated successfully at home. One of the best ways to speed up the healing process is to apply a warm facecloth to the boil for 10 minutes, three or four times a day. The heat increases the amount of blood circulating around the boil, which means more infection-fighting white blood cells are sent there.
After the boil has burst, cover it with a sterile gauze or dressing to prevent the spread of infection. Wash your hands thoroughly using hot water and soap because this will help to prevent you from spreading any bacteria to other parts of your body or to other people.
Over-the-counter painkillers, such as paracetamol or ibuprofen, can relieve any pain caused by the boil.
See your doctor if you have a larger boil that feels soft and spongy to the touch (the medical name for this is a fluctuant boil).
Once a boil becomes soft and spongy, it is unlikely to burst open by itself and probably won't respond well to treatment with antibiotics. Your doctor may be able to remove the pus using a technique called incision and drainage. In some cases, your doctor may refer you to your local hospital for this treatment.
Incision and drainage
involves piercing the tip of the boil with a sterile needle or
scalpel. This encourages the pus to drain out of the boil, which
should help to relieve pain and stimulate the recovery process.
Before having the procedure you're likely to be given a local
anesthetic to numb the affected area.
Never attempt to
squeeze or pierce the head of a boil yourself because this can spread
the infection.
Antibiotics are usually recommended:
for all cases of carbuncles
if you have a high temperature
if you develop a secondary infection, such as cellulitis (an infection of the deeper layer of the skin)
if you have a boil on your face; facial boils have a higher risk of causing complications
if you're in severe pain and discomfort
A seven-day course of an
antibiotic called flucloxacillin is usually recommended, which is a
penicillin based antibiotic.
If you are allergic to penicillin
then alternative antibiotics, such as erythromycin can be used.
It
is important to finish the course of antibiotics even if the boil
goes away, as not doing so, could lead to a return of infection.
The boils can be contagious in some cases. Hence, if the boils are not handled appropriately, the chances of the boils spreading to the other areas increases immensely. If the boils are small and there is no infection or illness, which is plaguing the body currently, the boils will go away on their own in a week's time. However, if they are very painful boils treatment at home is the best option one has on hand.
One of the easiest boils treatment is to take hot showers twice or thrice a day. The heat and moisture often proves to be helpful in opening the boil and draining. However, it is important that you do not take a bath, as the chances of the infection spreading to other parts of the body increases. If taking showers twice or thrice a day is not possible, there is another boils home treatment, which you may want to use. Use warm water to heat the boil. You can also make use of heated cloth piece. Repeat this three to four times for 20 to 25 minutes each time. This will also help in opening of the head and drainage of the boil.
A lot of people ask how to cure boils, but they do not take the requires measures for the same. Many times, when the immunity power of the body reduces, there can be skin eruptions. Hence, when there is an occurrence of a boil, start taking a vitamin C supplement everyday. This will help to boost the immune system and to get rid of the boil.
Among home remedies for boils, this home remedy is effective. The name of this remedy is boils treatment using garlic and onion. Use either garlic juice or onion juice on the boils. This will help to ripen the boils. When they ripen, opening the head and draining them will be easy. You can also combine garlic and onion juice in the ratio 1:1 to derive the best results.
For boils treatment of skin on the face, you can make use of turmeric. You can simply apply turmeric on the boil, which will help in speeding up the healing process. If you like it, you can also consume turmeric in hot water first thing in the morning and also at bed time. It will help to get rid of impurities, if any, in the blood.
If boils are caused, because of unclean bowels, triphala can be taken to help in cleansing the bowels. It should be taken with hot water at bed time. At the same time, you may want to go through a detox diet to get rid of the skin boils. Ensure you consume a lot of leafy green vegetables, fruits in your diet to keep the system clean.
If you still have the question, how to get rid of boils using home treatment, then you may want to use parsley for the same. Parsley leaves steeped in boiling hot water and used as a poultice on the affected part will prove to be of help in treating the condition.
For further answer to the question, how to treat boils at home, make use of cumin seeds paste to be applied on the skin. Before you make the paste, roast the seeds for a minute or two. If you do not roast the seeds, chances are high, that you may not be able to make a paste with it.
Tea tree oil, which is extracted from the leaves of the Australian tea tree (Melaleuca alternifolia), has been used for centuries as an antiseptic, antibiotic and antifungal agent. It's also used topically to treat boils. Tea tree oil can cause allergic reactions in some people, so be sure to stop using it and tell your doctor if you have any problems with its use.
Along with these boils treatment at home, make sure you follow a healthy life. Your routine should have some form of exercise. It will help to throw the toxins out of the body. Make sure you maintain good hygiene, so that the boils do not spread to other parts of the body.
Scarring can sometimes occur following a larger boil or carbuncle. While scars never disappear completely, they do fade with time and become less noticeable.
The bacteria inside a boil or carbuncle can sometimes spread to other parts of the body and trigger a secondary infection.
Cellulitis is the most common secondary infection associated with boils and carbuncles. Cellulitis is an infection of the deeper layers of the skin.
Much less common secondary infections associated with boils and carbuncles include:
septic arthritis – an infection of a joint
osteomyelitis – an infection that develops inside a bone
endocarditis – an infection of the inner layer of the heart
septicaemia – an infection of the blood
brain abscess – a collection of pus develops inside the brain
These less common secondary infections need to be treated with injections of antibiotics. In the case of septicemia and brain abscess, admission to an intensive care unit (ICU) may be required.
In some cases, bacteria from a boil or more commonly, a carbuncle, can enter your bloodstream and travel to other parts of your body. The spreading infection, commonly known as blood poisoning (sepsis), can lead to infections deep within your body, such as your heart (endocarditis) and bone (osteomyelitis). Blood poisoning itself — which is characterized by high fever, rapid breathing and elevated heart rate — can lead to septic shock, a life-threatening state of extremely low blood pressure.
Another potentially serious problem is the emergence of drug-resistant strains of Staphylococcus aureus. Up to half of the staph bacteria found in hospitals are resistant to many commonly used antibiotics, including methicillin. Methicillin-resistant staphylococcus aureus (MRSA) has led to the use of alternative antibiotics, such as vancomycin, but some strains of staph bacteria have become less susceptible to vancomycin, too. Although MRSA is often acquired in a hospital setting, it can be spread in the general community, as well.
Cavernous sinus thrombosis is very rare but potentially life-threatening complication of a boil. It occurs when an infection triggers a blood clot in the spaces behind the eye socket and the clot begins to increase pressure on the brain, causing symptoms such as:
a sharp and severe headache
swelling of the eyes
eye pain that's often severe
Without prompt treatment with antibiotics, cavernous sinus thrombosis can be fatal. However, it should be stressed that only 1 in every 2.5 million people in England will develop this complication in any given year.
Although it's not always possible to prevent boils, especially if you have a compromised immune system, the following measures may help you avoid staph infections:
Wash your hands regularly with mild soap. Or, use an alcohol-based hand rub often. Careful hand washing is your best defense against germs.
Thoroughly clean even small cuts and scrapes. Wash the wound well with soap and water and apply an over-the-counter antibiotic ointment.
Keep wounds covered. Keep cuts and abrasions clean and covered with sterile, dry bandages until they heal.
Keep personal items personal. If you share personal items, such as towels, sheets, razors, clothing and athletic equipment, always wash before using to avoid possible infections. Staph infections can spread via objects, as well as from person to person. If you have a cut or sore, wash your towels and linens using detergent and hot water with added bleach, and dry them in a hot dryer.
