not all (middle) ear infections respond to amoxicillin and because you could not take the recommend dosage you are going to need an alternative antibiotic (perhaps a stronger one that is not so hard on your gi tract). please call your doctor for a change in your therapy because you also have a sinus infection that needs treatment as well.
ear infection. im an adult. got a cold 2 weeks ago thought i was getting better but then sinus trouble began. was in urgent care 3 days ago sinus infection confirmed put on 2000 mg amoxicillin. i didn't tolerate that dose without bad diarrhea- so i cut the dose in half. 2 days (yesterday) after starting it i woke up with 1 ear plugged solid today very painful. nurse at work confirmed that my ear was "red and bulging". i have about 40 % hearing ability between both ears and am miserable. what to do now?
