What happens if your antibiotics (amox-clav x10 days) dosent clear up your sinus infection/ear infection?

Sinusitis: Sinusitis usually a self-limiting disease and doesn't require Antibiotics but if the patient has fever, looks sick, non-Antibiotics treatment not worked, history of sinusitis before then Antibiotics recommended, if you are not getting better you might need another kind of Antibiotics or you need further imaging to evaluate your sinuses better, talk to your provider, see an ENT if not better.

See physician for: If you still having fevers, pain and general malaise, I suggest you see your prescribing doctor or your local ENT specialist for reexamination. They may need to prescribe a different antibiotic and/or additional medicines to help resolve your symptoms.

Partial treatment: Sinus infections can be harder to treat than other infections. The sinuses are air filled cavities or spaces in the skull with a lining of tissue. The blood supply to this lining is not as good there. Antibiotics may have to be given for longer periods to get enough of the drug into the sinuses to kill all the germs. Sometimes certain germs are best treated by a different antibiotic. See your doc
