Thanks for posting your concern on HCM! I can understand your problem. I am of the opinion that the cause for the recurrent breast abscess could be due to inadequate drainage of the pus from the pus filled cavities (loculi). If the loculi are not drained or excised properly then abscesses are bound to recur. Since the organisms isolated are gram positive cocci (most commonly staphylo cocci) and the fact that most of these organisms are resistant to penicillins, the antibiotic of choice for such infection would be Ceftriazone along with tazobactam. Ringworm is caused by the fungi, which is treated by antifungal cream like clotrimazole or Terbinafine. Regards!
