Do i have an ear infection?

I've noticed the last couple days I've been getting pretty dizzy, I could be standing or sitting and all of a sudden I'd be super dizzy.. Last night I cleaned out my ears with peroxide. I dropped a couple drops in each ear and let them bubble, then let it drain onto toilet paper. I didn't stick anything in my ear, and this is how I always clean them. Well shortly after I noticed my left ear started to hurt, like a dull pounding almost. Well all night it hurt and it would switch between a sharp pain and a dull pain, and kept me awake mostly.. it also kinda feels like something is in my ear and its warm in there..

is this an ear infection? I haven't taken any pain pills, but I do have some and antibiotics also..
