Bu my question for you is: do you mean that even a PERFECT equalization would not stop the pain, being depth ear pain independent from equalization effects?
No, this is not what I meant. First, by eq. technique I mean not only frenzel/valsalva, but pace of eq., rate of descend, head position, eq. on the surface and everything else that will make you equalize properly, this could differ from person to person. The pain is usually caused by negative pressure inside your middle ear compared to its surrounding (=water at depth). The negative pressure "pulls" your eardrums inside thuss causing pain (eardrums is usually the case, but other middle-ear tissues can be hurt by this as well). What I meant is that bad eardrums could be
more sensitive (the other way around can also happen). The solution should be to avoid negative pressure inside your middle ear as much as possible = equalizing. If you are feeling pressure in your ears - you equalized too late by my book. If you hit an equalization block, also. That happened because you let the negative pressure build inside. What I think you should do is to equalize as often as possible - keep your hand on your nose, equalize even 2-3 times a second if you have to. Descend more slowly if you have to. Don't equalize forcefully, if you need to do that you have probably failed technique-wise, just ascend, there's always the next dive.
Frenzel can be more effective than valsalva in some cases, one of the reasons I think is because the 'tongue piston' maneuver also moves other tissues around your soft palate and can affect the opening of your e-tubes.
I think pain is not to be settled with so easily, and I think most cases have a solution.
I suggest that maybe you should try line diving for a few times, and eat out for a night or two
(as in, keep the gun at home).
Practice the different variables in equalization like descent speed and eq. pace (as well as your Frenzel).
Another problem could be eq. volume - you're not putting enough air with each equalization, thuss creating a debt (small negative pressure) that grows with depth, till you hit a wall (of pain or equalization).
Equalization volume can also be juggled with, but not if you're already equalizing forcefully. On the other hand pace and rate of descent can usually solve this so suggest first starting with them, as increasing equalization volume will not solve the problem of negative pressure between equalizations (which is probably your main problem).
After you played with variables and found something that works you can try fine tuning them to suit your (new) dive style.
I know this is probably very frustrating, but I think it should be possible to solve this problem once and for all. And you better solve it, after I wrote so much.
If there's anything unclear in this or the prrevious post (and the ones it directs to) ask. I think every diver should understand how this works.
