Signs and Symptoms
A red-to-purple, tender lump on an area of the skin that also has hair. The most common areas for boils to occur are places where there is friction and/or places that tend to be sweaty, such as the buttocks, armpits, groin, neck, shoulders, and face. The skin surrounding the lump may look swollen and red. The center of the lump eventually becomes filled with yellow or white pus that you will be able to see (called "coming to a head"). The pus is a mixture of bacteria and infection-fighting white blood cells.
