What Causes Cold Followed By Hearing Loss And Flutters In Left Ear?

Yes. I had a bad head cold in December. In late January I lost my hearing in both ears. I went to the doctor and she thought I might of had a sinus infection and a double ear infection she prescribed a z-pack. Two a-packs later and a round of amoxicillin my left ear is still fluttering and it is now the middle of March. I m 41yrs old and healthy. My ear flutters all day long and all night long. Hard to sleep. What s going on? What should I do?
