Twitching eardrum

Hi! I’ve been using the Quiet loops for a couple months now when i go to sleep, in the last 3 days I’ve noticed that my left eardrum inside seems to be “twitching” I can’t quite describe the sensation but that’s as close to it as I can get..

It continued throughout the day on day 1 but then on day 2 and 3 only happens in the morning then eases off after Half an hour, I’m suspecting it is due to wearing the loops all night but it’s only in my left ear?

Anyone had any similar experiences?
