i used to get ear infections like it was my job. it's not abnormal for one to have hearing loss for a while. my hearing would occasionaly be impaired for up to 2 weeks. i've heard tell of it lasting a month. sometimes it's not neccesary to take antibiotics for ear infections, as they go away on there own, but since youv'e started, make sure to finish the prescription or else you can develop antiobiotic resistant situations which suck
