What should i do? i think i have MRSA, the abscesses/boils keep coming back!!?

About a month ago i was in the ER and the doctor told me he thinks i have MRSA and to make an appointment with a local doctor, i was prescribed antibiotics until i could get to a regular doctor. i finished the antibiotics and the abscesses/boils went away, I made an appointment with a local doctor but the soonest they could get me in is august 16th and the abscesses/boils have come back and are very painful. should i just wait it out until august 16th or should i get to the ER??
