Hi J.! I've never heard of MRSA however these symptoms sound like the staff infection my nephew keeps getting. I feel so sad that she's in pain...maybe you should try an ointment containing benzacaine; like anbesol. I know that sounds silly but Lanacaine and benzacaine are numbing agents that may relieve some of her pain. Benzacaine is one of the strongest numbing agents you can get w/o a rx. Good luck. C.
