I too sometimes get eardrum twitching. In addition to it, I occasionally have something called tensor tympani syndrome, a benign condition in which my ear flutters when I hear a loud noise. Here is a helpful link on that: I've had both for years. I remember going to ear doctors and neurologists back in college, over a decade ago, to get answers. The told me that stress plays a large part, and one told me he could sever the tiny muscle or Botox it if it really bothered me. I declined and it went away on its own but sometimes returns if I have allergies or am stressed. My dad doesn't have tensor tympani syndrome, but he says he sometimes gets eardrum twitches too and he has for decades. Along with tongue twitching, I'd say eardrum twitching is the worst in terms of being annoying, because the feeling of a bug flapping its wings in your ear is just not good.Incidentally I had a follow up with my neurologist two weeks ago, not about bfs but about other stuff ( weakly positive ANA, and restless legs). Another thread here on eardrum twitching piqued my interest, so I asked her and she said that yes, eardrums do twitch, and yes it's likely part of the BFS picture. Then we didn't talk about bfs because she, like most neurologists, are just not concerned about it after everything comes back clean. Kind of funny really, we should all be so nonchalant about it.
