Symptoms. People who suffer from MRSA will often see a skin infection before anything else. The most likely areas to suffer are those which have a lot of body hair. This includes the armpits and back of the neck. Symptoms can also occur anywhere a body has recently been cut or had other damage occur to the skin. The skin is the main barrier for bacterial infections. These skin infections tend to swell and be very painful on the bump. Some confuse it for large spider bites or large pimples. The area around the center will be red and warm (also called cellulitis). It’s very possible for fluids or pus to drain out of the infected area. In addition to the skin infection, some people also form a high fever.
