When I Open My Mouth or Smile, My Eardrum Vibrates and Feel Some Pain — Is It a TMJ Issue?

I feel that my eardrum vibrates, when I open my mouth a lot or when I smile. It is almost imperceptible unless I have the earplugs on.

Does this have to do with a TMJ issue? I also feel pain, so I think there may be some jaw problem.
I also thought it could be due to a small lesion in the eardrum, although all the doctors I went told me that my ear was ok.

I don't know how accurate are the tools they have to determine if the eardrum is healthy...

Thanks!

 

I believe that facial nerves can get irritated or even paralyzed after nerves in the ear are damaged.

This is documented in cases of auditory neuroma (audiotory nerve tumors)

Facial numbness and very rarely, weakness or loss of muscle movement

It is no coincidence if someone experiences jaw aches/numbness that mimics TMJ after being exposed to very loud noise.

 

Bumping this--I have the exact same issue. Never had TMD or jaw pain before. Then an ear infection on plane led to flutters. A few weeks later, I went to a nightclub and walked out with tinnitus, worse spasms, and the next day developed classic TMD symptoms. Jaw/ear muscles hurt when I talk, smile or chew, I get some fluttering, and have a low frequency drone on top of high frequency tinnitus.

Had a TMJ MRI and CT (both normal) and wore a nightguard for 6 months. Had no effect. I no longer have burning facial nerve pain, which is nice. Just muscle aches from talking, laughing, smiling etc.
