Fuck school! Yeah...woot! You want fries with that?
I'm just afraid the continual course of antibiotics are doing more harm than good. In my (completely unprofessional) opinion, it would seem that surgery is your best option.
Besides, how many days have you been to school in the last couple of weeks? With today's scope technology, most surgeries can be done as an outpatient and you might be back in school quicker than another round of antibiotic house calls.
