i was looking at this, and just realized that the noise is indeed that when i yawn hard enough. but it's heavily focused on one side of my head.
is your hearing coming back ? this happens to my ear after i go swimming , from my previous experience with my ENT doctor , i had a middle ear infection
wait it out , if it starts getting painful go see a doctor.
the ocean/air noise has been fluctuating up and down for nearly two hours now, but hasn't gone away.
i finally got to the nurse and she checked for an ear infection, but couldn't see anything. it doesn't hurt like an ear infection, anyways, it barely hurts at all.
the noise still hasn't gone away completely, days later.
