Not sure but I'm thinking it might have to do with the ear canal being inflamed or smaller than normal and the blood not being able to flow properly. I didn't have this until after an accident. It's happening right now as I type and it's just my left ear.

Interesting point. It always starts in my left ear and an ENT did note that my left ear canal is "malformed" and much smaller than my right.
