MRSA is a type of staph, so the symptoms of a MRSA infection and the symptoms of an infection due to other staph are the same. Pimples, rashes, pus-filled boils especially when warm, painful, red or swollen can indicate a staph skin infection. Impetigo is one example of a skin infection that can be caused by staph, including MRSA. Staph, including MRSA, can also cause more serious infection, such as severe skin infection, surgical wound infections, bloodstream infections and pneumonia. Symptoms could include high fever, swelling, heat and pain around a wound, headache, and fatigue.
