Is there a big hard lump in the navel of the abscess?

Pustules are a very common disease. For example, if you have acne on your face, some small pustules will have pustules, but if the pustules are large, there will be large lumps inside after squeezing them. In this case, most of the time, they are furuncles. Furuncles are an infectious disease deep in the hair follicles. Generally, anti-infection treatment is required during treatment. If the infection worsens, surgical treatment may be required.

Causes of Furuncles

Furuncle is an acute suppurative infection of a single hair follicle or sebaceous gland in the human skin caused by bacterial infection (usually Staphylococcus aureus). It is particularly likely to occur in the head, face, neck, armpits and buttocks of the human body. When a boil first occurs, it is red, swollen, hot and painful. When it matures, a small yellow-white pus head will appear in the center. It will heal after it ruptures on its own and the pus plug is drained. However, if it is not handled properly, such as by squeezing it randomly, the bacteria may enter the brain (cavernous sinus or meninges) with the blood, causing serious complications, and the condition will be very dangerous. In addition, children with malnutrition and weak resistance may have repeated illnesses, which may lead to the furunculosis stage, making treatment difficult.

Furuncle is an acute suppurative infection of a single hair follicle and its sebaceous gland caused by the invasion of bacteria such as Staphylococcus aureus and Staphylococcus epidermidis from hair follicles or sweat glands. Inflammation often extends to the surrounding subcutaneous tissue. Under normal circumstances, there are some bacteria in the hair follicles and sebaceous glands of the human body. Only when the systemic or local resistance is reduced can these bacteria multiply in large numbers and boils will occur. Sugar metabolism disorders and weakened physical constitution are the internal causes of furunculosis, while skin abrasions, uncleanliness, or frequent friction and irritation are the external factors of furunculosis. This disease can occur in any part of the body with hair follicles, but is most common on the head, face, neck, chest, back, and arms. The disease occurs throughout the year, but is most common in summer.

Symptoms of boils

Boils initially appear as painful red papules the size of a grain of rice, which are painful to touch. Later, it gradually expands into a hemispherical dark red nodule, causing conscious pain and tenderness, swollen nearby lymph nodes, and general discomfort. After a few days, the center of the nodule softens and feels fluctuating to the touch, and a yellow-white pus head may appear on the top. There is still an induration at its base. After an abscess is formed, it often bursts on its own, discharging necrotic tissue and pus, and the pain is immediately relieved. The redness and swelling gradually subsided, and after about a week, the wound healed, leaving a scar. Some boils do not break and are gradually absorbed, but the nodules take a long time to heal. The pain is more severe before the furuncle matures, especially when it occurs in the external auditory canal. Those that occur in the nose, lips, etc., commonly known as the "triangle area", generally have severe symptoms, often accompanied by systemic symptoms such as fever. The nearby lymph nodes are often swollen and painful, and need to be treated in the hospital's surgical department. Chronic multiple furunculosis has no fixed course of disease, often recurring, one after another, and can last for months or years without healing. It is common in malnourished children or diabetic patients.

Although boils are not a very serious disease, because the hair follicles are closely adjacent to each other, if the boils that have already grown are not treated in time, they will not only be extremely painful, but will also easily cause infection of the surrounding skin and cause more boils to grow. Furuncles often occur in areas of the body that are under pressure, such as the neck collar or buttocks. During the formation process of boils, there is often severe throbbing pain, especially if the boils grow on the forehead or jaw where the skin tissue is dense and the tension is high, the pain will be more severe. Generally, after one or two days, a pus plug will form in the center of the red swelling, and it will burst on its own after two or three days. Some boils may disappear on their own without rupturing.
