4-5 months ago, i developed swimmers ear, both ears. Oral antibiotics and drops, it went away. Month later, struck again, drops and it subsided, but didn t disappear. Now, it s clear sticky discharge, fishy smell. No fever, dizziness (not constant) ringing at times but i generally feel fine. I have a refill for cyprodex, is that enough or should i go back and get oral antibiotics?
