Suggest Medication For Red And Infected Ears During Productive Cough

hi, ive had a productive cough for a week and a half, and for a week my ears have felt like ive got glass tumblers over them and i cant hear properly, and i can hear washing machine swishes if i sit in a quiet room, went to the docs 5days ago and was prescribed amoxicillin as my ears were red and infected, hasnt made any difference at all, and its starting to get me down anything else you could suggest? im suposed to be going for a gen anesthetic in a week for 4teeth out but cant see it happening if im still like this.thanks
