Boils in the groin


An antibiotic ointment can help with boils in the groin.

Boils are purulent, bacteria-induced inflammation of the hair follicles in the hairy area of ​​the body. In addition to the face, the groin and genital area are also often affected. The boil occurs when hair follicle inflammation develops (Folliculitis) worsens and forms a pus-filled lump in the skin, up to several centimeters in size. This is enclosed in a capsule and can develop into an abscess in the groin. If boils appear again and again in the same place, one speaks of one Furunculosis. This occurs mainly in patients with an immune deficiency.

Causes of a boil in the groin

Boils occur when bacteria that otherwise only occur on the surface of the skin penetrate the skin and mainly infect the hair roots. This initially causes inflammation of the hair follicles, which if left untreated can turn into a boil.

One of the typical places where a boil tends to develop is the groin and genital area. Especially when using wet razors, microtraumas arise here, which enable the pathogens to penetrate the hair roots.

Since this area is also constantly covered by clothing, heat and moisture encourage bacteria to multiply here. The skin folds in the groin also contribute to the development. If the hem of the underwear then runs over an infected area, this is not only painful, but also makes the symptoms worse.

Patients with diabetes mellitus or other immunodeficiencies, such as e.g. AIDS. Even very overweight can promote the development of boils, especially in the groin, as the increased skin folding promotes bacterial growth.

What role do the lymph nodes play in the development of a boil?

If a boil is not treated, the bacteria can spread to the neighboring lymph nodes and cause inflammation there. In the worst case, this can then spread further via the lymphatic system and up to a full screen sepsis, so develop blood poisoning.

However, especially in the groin, the lymph nodes themselves can be noticed as swollen nodules. Since important lymph stations for the legs run here, these are generally also affected by infections in the leg or genital area. Unlike a boil or abscess, these are not overheated or inflamed. The pus filling of a boil is also a clear delimitation criterion.

The therapy

Most often it is possible to treat the furuncle of the groin with antibiotic ointments and disinfecting solutions.
If local treatment is insufficient, it may also be necessary to surgically open the boil. After that, it is important that the wound heals well from the inside out and that it is treated with antibacterial agents to prevent the recurrence of a boil.

Many methods from the field of natural medicine are also supposed to promote the emptying of the boil (see home remedies). As a further addition, the so-called train ointment (e.g. Ichthiolan), remove the pus from the boil. If lymph nodes or even entire lymphatic tracts are already affected, local therapy must be supplemented by systemic antibiotics. Simple penicillins or cephalosporins are usually used for this purpose.

In any case, a boil should not be treated on your own for too long in order to prevent further penetration of the germs. If the boil becomes larger, more painful or the reddening spreads during treatment attempts, a doctor should definitely be consulted.
