Yeast infection?: Possibly a yeast infection, especially if you are uncircumcised. As I said in a previous reply, this is a pretty atypical antibiotic combination. It's very broad spectrum, i.e. inhibits a very wide range of bacteria. Suppressing natural bacteria often promotes overgrowth of yeast (fungi). Don't try to diagnose and treat it yourself. See the doctor or clinic who prescribed the antibiotics.
