Furuncle: symptoms and areas of the body that can be affected

The boil is an infection on the skin caused by the bacterium Staphylococcus aureus . Here’s how to identify the symptoms:


The main symptom of boils is an abscess on the skin. Abscesses are accumulations of pus caused by infections. They are painful, reddened, swollen, hardened nodules that have a yellowish center, which indicates the presence of pus.

Often the lump breaks on its own and the pain goes away. It also passes immediately in cases where the abscess is surgically opened.


The skin around the boil may itch. Avoid scratching, as this can help spread the bacteria, turning the isolated case into furunculosis.

Which areas are affected?

Any part of the body that has hair follicles can be affected by boils and that means almost the entire body. However, they are more common in some regions such as the armpits, buttocks, face, thighs or in the genital region. This is because these regions are more prone to exposure to moisture and grease, in addition to the friction of the clothes that cover the region.
