Furuncle - acute purulent inflammation of hair follicles, sebaceous glands and surrounding tissue. This is one of the most common skin diseases. When inflammation occurs chronically, over several months or years, when the boils are at different stages of development and constantly appear new, then a condition called abrasions.
Why do I get boils
Staphylococcus aureus - a microorganism which provoke the appearance of boils. Every fifth person in the world - a permanent carrier of this bacterium, which is kept on the skin and mucous membranes of the upper respiratory tract. Much less often boils caused by staph white.
There are external and internal factors that predispose to the occurrence of boils. These include:
- Slight damage to the skin (eg, scrapes and scratches);
- Friction uncomfortable clothes;
- Diseases with metabolic disorders

- Diseases of the gastrointestinal tract;
- Continual hypothermia or hyperthermia;
- Endocrine and nervous diseases;
- Alcohol abuse;
- Glucocorticoid hormones and drugs for chemotherapy

Men boils occur more frequently than women. In children, this condition is rare. In many cases, boils appear in spring or autumn.
Inflammation of the hair follicle is the primary and secondary. In the first situation, furuncle formed on healthy skin and in the second - becomes complication existing purulent diseases.
Furuncle in its development passes through three stages:
- Seals (of infiltration);
- Suppuration and necrotic (dying off);
The first step in place of infection around hair follicles formed inflammatory infiltrate that is sealed portion where the accumulated red blood cells and lymph. Externally noticeable redness with fuzzy boundaries, which gradually increases in size. Man feels tingling or pain.
After three or four days comes the second stage. At this time, the diameter of the boil is increased to three centimeters. In the center of the inflammatory infiltrate formed necrotic core, and in its visible surface pustule (abscess). Furuncle becomes cone-shaped and covered with smooth skin a bluish color.
Signs of intoxication: headache, malaise and weakness. Body temperature rises to 38 ° C.
Then the pustule opened, and stands out the contents boil. First out the pus, sometimes mixed with blood, and then the green-yellow necrotic core (it is composed of dead cellular elements). After a few days at this point formed scar. At first, it has a blue-red color, and then brightens and becomes unnoticeable.
Sometimes the process is erased character is formed only when the infiltration without festering. In debilitated patients in place furuncle can form an abscess
Abscess - why it is so dangerous ulcers?
(destruction of the surrounding tissue and the formation of pus-filled cavity).
Boils can appear almost all parts of the body. They do not happen only in the palms and soles, that is, those places where there are no hair follicles. Most often boils are formed on the skin that are exposed to constant pollution (forearm, back of the hand) or friction (back of the neck, lower back, buttocks and thighs).
Furuncle external auditory canal
Furuncle formed in the ear canal due to penetration of bacteria in the sebaceous glands and hair follicles. This usually occurs when skin irritation pins, fingers or other objects, especially those people who suffer from ear suppuration.
Man worried about severe pain that can give teeth, eyes, neck, or distributed over the entire head. Unpleasant sensations are amplified in speaking and chewing. This is due to the fact that the articular head of the mandible and periodically shifted against the walls of the external auditory meatus.
Also, there is a sharp pain by pulling the ear, pressing on the tragus (the small protrusion of cartilage in the ear) and the bottom wall of the ear canal. Rise located near the lymph nodes. There are weakness, headache, chills, body temperature rises.
If the boil is located at the entrance of the ear canal, it can be seen without the aid of special tools. In other cases, the inflammation is detected by a narrow ear funnel. In this section visible redness, which rises above the surrounding skin, and in the center is defined by purulent inflammation rod.
After maturing boil in most cases it spontaneously opened, and the swelling is visible when viewed with a hollow in the center, where pus. After that well-being is gradually improving, the pain disappears. On average, the disease lasts for about seven days.
Boils on the lip
Many people boils occur on the upper lip (in the nasolabial triangle). This localization of the inflammatory process is very dangerous. Infection can get into the superficial facial vein and then penetrate through the bloodstream to the brain.
Patients complain of high fever and severe headache. This is one of the signs of suppurative thrombophlebitis (inflammation of the vein wall to form the lumen of a blood clot in her) facial veins. Rapidly growing facial swelling, palpated dense painful vessels. In the future may develop purulent meningitis
Meningitis - an inflammation of the meninges
(inflammation of the soft meninges) or sepsis - spreading the infection throughout the body.
What is the carbuncle
Carbuncle - acute purulent inflammation of the skin and subcutaneous fat around a few hair follicles and sebaceous glands, which can quickly spread to the surrounding tissues. It most often occurs in areas of friction leather clothing. Carbuncles are located on the face, back of the neck, back and buttocks.
Some follicles may be affected simultaneously. In other cases, there is a single first boil, and then in the inflammatory process involved disposed around hair follicles.
The inflammatory infiltrate is increasing not only because of the defeat of healthy follicles, but also extends to deeper located tissues (muscles and bones). About five days after the onset of the bacteremia is a tight knot with a diameter of five to ten centimeters, clearly delineated from the surrounding tissue. The surface of the carbuncle has a hemispherical shape and dark red or purple color.
Man feels throbbing, "tearing" almost constant pain, which periodically strengthened or weakened and becomes unbearable especially when probing the inflammatory focus. After some time, around several follicles in the center of carbuncle develops necrosis. This blackens the affected area, there are multiple holes, from which it follows a liquid containing blood and pus.
Formed a shallow ulcer with jagged edges, which are visible at the bottom of greenish-yellow rods. Recent rejected much slower than single boils.
After separation of dead tissue formed deep ulcer with a bluish edges and the bottom of which is covered mucopurulent touch and bleeds easily. Around necrosis long time preserved seal tissue. Gradually the ulcer is cleaned and after two or three weeks scars.
If the disease is very difficult, then it appears chills, and severe headache, body temperature rises to 40-41 ° C. Around a dense carbuncle swelling, increasing situated near the lymph nodes and lymph vessels are inflamed.
In cases where a boil or carbuncle, located in the area of the spine, may be affected vertebrae and spinal cord. If inflammation of Education emerged at the back, sometimes in the pathological process involves the bones of the skull and the meninges. With the localization of a carbuncle on the chin may develop osteomyelitis of the mandible (purulent necrotic process in the bone and surrounding tissues).
