Still an ear infection
. Recurrent ear infection i suggest that you properly checked. Including test for immunocompetences such as even testing for HIV or diabetes Mellitus
or other underlying pathologies that could predispose to immunosuppression
. If you are immunocompetent and still having the recurrent ear infection then i suggest you should be placed on a cephalosporin
antibiotics ( 2nd or 3rd generation will be better). The germs causing the ear infection seem to be resistant to the amoxicillin. A steroid lotion or droplets could be applied on the ear to reduce pain and inflammation or oral antiinflammatory medications should be taken in association to the antibiotics.
Consulting an ENT specialist
if above fails is of paramount importance.
Wish you all the best and hope this helps
