Been taking augmentin (amoxicillin and clavulanate) since 6/11, for an ear & sinus infection. My ear feels full of fluid. How long before my ear drains?

Family practice . You may have eustachion tube dysfunction. Infection could be clearing but your ear still feels full. Try taking a decongestant. This may help resolve the swelling. See your dr if it persists longer than 2 weeks.
