What happened to the hard lump on the left side of my neck?

The body is a very important part of people, and the body often has some uncomfortable symptoms. Therefore, protecting the body and preventing various diseases are matters that deserve people's attention. For example, many people often have some hard lumps on their bodies, which are mostly found in the neck and other places close to the aorta. So, what's the matter with a hard lump on the left side of the neck?

It could be folliculitis or a boil. Furuncle is a purulent infection of hair follicles and the surrounding tissues deep inside the hair follicles. A carbuncle is formed when multiple adjacent hair follicles are infected, inflamed and fused. 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.

The initial clinical manifestations are local red, swollen, and painful nodules, 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. 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.

Early inflammatory nodules can be treated with hot compresses or physical therapy (thermolysis, infrared or ultrashort wave), or with topical antibiotic ointments, such as mupirocin ointment. When there is a pus head, apply carbolic acid on the top. When there is fluctuation, drainage should be performed as soon as possible. Immature boils should not be squeezed to avoid spreading the infection. The following four situations should be treated with systemic antibiotics: 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. Drugs that are sensitive to the pathogens, such as penicillin, cephalosporins, macrolides, and clindamycin, should be given.
