Hello kell7552:

I am currently having a problem with a herniated cervical disk. I have trouble typing; please bear with me. Dr D.

Many thanks to all who responded. Clearing in both directions is common among nondivers. Indeed, many people find it necessary to clear their ears , e.g., when traveling over mountains in a car. This is both going up and coming down. It is not strange.

hmm... i thought it had to do with my sinuses ... it only happens when i am stuffy

The times I experience it and am able to make the "block" go away, i get a drop of water coming out of my ear anyways..
It happens when i bathe in the lake or ocean as well btw.. Usually I can "shake" it out

I was diving a couple weeks ago and the DM/Instructor who thought it was odd that I paused for a second to clear my ears on the way up. Usually I can feel it popping in my ears on the way up so I don't have to clear but sometimes I do have to clear on the way up. Good to know it's not just me.

Watch out! That sensation of blocked ears after diving can be an indication of repeated ear damage by rupture of a thin membrane in the ear. Blocking on the name now but called the "?" window in the inner ear. May be an indication you need to pay more attention to your sinuses/clearing while diving.

See DAN site for details.

you might be talking about the round window which can rupture if you equalize using a forced valsalva maneuver

although if you were to rupture the round window you wouldnt be able to hear...

The loss of hearing appears to be Barotitis media, the most common ear injury. Rupture of the round or oval window are usually associated with vertigo and pain with some resultant hearing loss.

Dennis - When I perform the Emergency Swimming Ascent skill ten times in classes, once individually for each of my students, I can hear the air escaping from my ear. I consulted with a physician, and air escaping from my ear from behind the ear drum was the explanation. He checked, and I do not have a problem by his assessment. No perforation.

Best of luck..

Craig, We as instructors know the physiology of the air from the exam questions on the instructor exam amongst others. We should all know that the air we blow in to the air through the valsalva manouver (And which enters through the eustacian tube) also comes out the same way (Through the eustacian tube) - It's just that most people don't need to do anything to let the air out - This is because the overpressure in the eustacian tube tends to equalize continuously on the way up - Whilst on the way down, it doesn't. (We wait until there is an underpressure, and then we compensate until there is a very slight over-pressure - I guess the ear blows better than it sucks - I have a couple of theories why this is, but since I haven't checked, I'll keep them to myself for now..)

It's true that the air comes out of the ear, and that the air is initially trapped behind the eardrum, but come on - Around the eardrum??!
