MRSA (methicillin-resistant Staphylococcus aureus) is an illness that has become more common over the past several decades. When a person develops this type of staph infection, a red bump (or cluster of red bumps) may appear on the skin. The bumps may resemble a pimple, boil, or pustule.
MRSA skin infections commonly occur at sites of visible skin trauma, such as cuts and abrasions, and areas of the body covered by hair, such as the back of the neck, groin, buttocks, armpits, or beard area of men.
In most cases, an infection with MRSA is treated with antibiotics. Your healthcare provider may also drain some of the infected fluid by inserting a needle into the skin. Serious infections may require hospitalization and IV antibiotics.
