I had a cold about 2 months ago. After a couple weeks I started having problems with my left ear stopping up at night after I slept. After a few hours being up it would open & I would be fine. In the last 2 weeks it has began stopping up and causing dizziness and nausea. I went to my primary care provider who said I had fluid in both ears but much more in my left ear and I was given a 5 day zithromax & steroids. It seemed better for about a week and now I m right back to where I was, and I also have painful echoing around louder noises in the ear as well. Not sure what to do or what is causing it. I also have allergies, which last year round. Any advice?
