About 2 months ago, I woke up one morning with dizziness. In the following days, it improved to the point that I was only dizzy when moving my head. The dizziness was completely resolved in 4 weeks. The entire time, I've had ear popping when swallowing, yawning, talking, etc. I have to sniff to get my ear "right" again. Now, for the past 3 days I've been experiencing throbbing pain around the same ear, but not in the ear. It's around my ear and temple area, and the throbbing is not constant, but it will throb for a few seconds and is random and intermittent several times an hour. It will always throb for a few seconds when I get up from a sitting position or move suddenly. Any ideas what this is?
