As SWATDOC said MRSA can only be diagnosed through a culture, which generally takes 48 hours to get results. If you told you that it is MRSA without culture results, he is assuming it is.
Most superficial MRSA infections can be treated with topical Bactroban, but the 3 antibiotics is overkill in my opinion. Most of the time MRSA can be effectively treated with Bactrim or Clindamycin.
Overuse of antibiotics is partially what has led to the prevelance of MRSA today. It originated in hospitals, but now (a slightly different strain) has spread into the community.
My guess is he is empirically treating you for MRSA without a clear definitive culture result. If he has culture results he should have a specific antibiotic that will treat this infection without having to use 3. Also if the wound is left open, you can be taught how to change your dressing and pack the wound properly in order not to have to keep returning to his office for extra charges.
