Does anybody elses eardrum ever twitch?
Yes, mine does that sometimes! It’s weird, because it messes with your sense of hearing. It makes an odd little thumping. I think it’s just like any other muscle twitching (I know the eardrum is a membrane, not a muscle, but there are muscles around it that are what are actually twitching). Than can mean a magnesium/calcium/potassium imbalance. I’ve noticed it happens when I’m either really tired or the day has been hot.
