You know when your foot falls asleep because you've sat with your legs crossed too long? I get a single "pin" of that "pins and needles" feeling in both of my ears on occasion (not at the same time though).
The one that was really getting to me this morning was a "whoosh" or "thump" feeling in my left ear. It was like I had a little person in my ear opening and shutting an umbrella really hard. (I have such a weird way of explaining things somethings. lol)
