that doc must have got his license to practice medicine off the internet too. what a goofball. antibiotics is the way to go with that. ive seen docs give people (antis) before with no real symptons of anything. just a precautionary measure if for no other reason. you would have thunk that he would have taken a sec to write you a script to be on the safe side.
or maybe he just wanted to charge you for 2 doc visits instead of 1.
and good luck with that.
