I have inner ear infection, sinusitis and vertigo. What to do?

Hello doctor,

I think I have an inner ear infection. I went to the doctor last year and he asked me about my symptoms. I told him and he said I had a viral thing in which he gave me antibiotics to take which I did not take. When I got my summary it is said that I had sinusitis. Now until this day my sinuses have been bothering me. The doctor said I had fluid in my left ear. I think the fluid in my left ear is causing me to feel bad. Last weekend I was laying on the couch on my right side and turned to my left fast over and saw the pictures on the wall go by when I turned fast. I tried in the night to lean back in the recliner part on the couch and had the same feeling almost, but I sat back up. I also have that feeling when I bend down but not a lot. I am worried and want to get relief for my left ear. What I just described to you is it a certain type of vertigo?
