People attach great importance to their buttocks, because from the perspective of image, the buttocks is an important part of people's charm, and from the physiological perspective, it is the basic tissue that helps people complete a series of actions such as sitting and standing. The buttocks in particular bear tremendous pressure when people sit or stand, which relieves people's fatigue. However, sitting for a long time will bring great harm to physical health. For example, why do pimples appear on the buttocks after sitting for a long time?

This thing is called furuncle, which is a purulent infection of hair follicles and the surrounding tissues deep inside the hair follicles. Staphylococcus aureus is the most common pathogen. Recurrent furunculosis in the anogenital area may be secondary to anaerobic infection. 5% are sterile and caused by a foreign body reaction, such as a ruptured cyst. It is more common in teenagers. Susceptibility factors include long-term carriage of S. aureus, diabetes, obesity, poor hygiene habits, and immunodeficiency status.

Clinical manifestations

Initially, small red, swollen and painful nodules appear locally, which gradually swell and become cone-shaped. After a few days, the center of the nodule becomes soft due to tissue necrosis, and small yellow-white pus plugs appear; the area of ​​redness, swelling, and pain expands. After a few more days, the pus plug falls off, the pus is discharged, and the inflammation gradually disappears and heals.

There are generally no obvious systemic symptoms. However, if it occurs in an area rich in blood and the body's resistance is weakened, it can cause symptoms of toxic blood such as discomfort, chills, fever, headache and anorexia. If boils on the face, especially around the upper lip and nose in the so-called "danger triangle", are squeezed or pricked, the infection can easily enter the cavernous sinuses in the skull along the medial angular vein and the ophthalmic vein, causing suppurative cavernous sinusitis, with progressive redness, swelling and nodules extending to the eyes and surrounding tissues, accompanied by pain and tenderness, headache, chills, high fever and even coma. The condition is very serious and the mortality rate is very high.

Antibiotics should be used systemically in the following four situations:

1. Folliculitis is located around the nose, in the nasal cavity or in the external auditory canal.

2. Large or recurrent furunculosis.

3. There is cellulitis around the lesions.

4. The skin lesions do not respond to local treatment.
