... ear had started aching. The pain went away a day after taking the first dose (2 tablets). Since taking the last dose yesterday, I woke this morning with a plugged ear and a slight ache. I know the medicine is suppose to continue to work in your system for the next 5 days, but if my ear is starting to hurt again, should I see my doctor to start another set or wait 5 days for the medicine to continue to work?
