How long is it supposed to it take an ear infection to go?

Depends: During any ear infection there is a temporary reduction in hearing due to the muck in the middle ear for up to 2-6 wks.If the infection & muck is not cleared out within 90 days that muck can turn to a glue like material.Some infections clear without meds, some benefit from having the muck removed & ventilation tubes placed. Most hearing will return to baseline.
