When I yawn my right ear rumble and thumps

Hi there, I’m experiencing the same thing going on 2 months now- I’ve been to ENT and it turns out I have patulous Eustachian tubes (probably due to being underweight), but the thumping I do have every time I yawn burp etc. what it is is the tensor veli palantini muscle that’s connected to the ET, either it could be a form of myoclonus or TTTS. There’s not a lot they can do and often confuses drs, however, taking magnesium citrate does help somewhat or muscle relaxers. Continuously yawning swallowing does aggravate it and certain neck positions as well.
