MRSA boils usually appear as red and swollen lesions that resemble spider bites or pimples on a person's skin, according to Mayo Clinic. The boils may ooze pus and usually appear next to skin recently broken by a cut or scratch.
MRSA boils also commonly form on parts of the body that hair covers, states Mayo Clinic. These locations include the back of a person's neck, groin, armpit and beard if a person is male. If a person suspects a MRSA infection, he should see a doctor as soon as possible for treatment because the disease spreads through skin-to-skin contact as well as through contact with contaminated surfaces.
