If it is swimmers ear its fine mate, just get some "œaqua ear" in there or what you are making up, straight after the dive. The reverse squeeze doesn't apply here at all, that's inner ear, and swimmers ear is outer ear!
I have had both ears operated on for just that from damage from too much cool waters from surfing and diving most of my life from 1969, around Auz from 74 to 77, down south is a killer for your outer ear.
Causal swimmers ear is the cold gets in and the bone reacts between ear drum and out side and builds up and then traps the waters and the dead plankton forms some revolting bacterial issue and the pores open up from it being so wet in there and in goes the bacteria, resulting in swimmers ear. Pools are worse with most folks peeing in there, yuk and in your ear it goes!! Much more goes into local pool waters, but we wont discuss those!
For my first ear op in 81 they took the ear semi off and drilled it out where it is closing up and that takes away some of your hearing just like industrial deafness "œringing in your ears" then they sow it back on and it leaves a tiny scar line at the back of your ear and hopefully they did not cut through the facial nerve that if they do your face droops on that side for ever!
When I came out of theatre my face was drooping the first time and they could not wake me up I was told, it was touch and go that time.
The next one I kept using aqua ear for years and was using a hood and till it was more or less closed up, they did it all in through my ear in 2001, no ear off that time but still left with some ringing as well.
At my worst both ears closed up and I was deaf except sounds through my scull for three days.
A squeeze is with your sinuses or antrums, where I did my junior dive course a poor guy came clambering out onto rocks in total panic when I was a young teenager one day as his mask was half full of blood from a squeeze he tolerated going down and it burst blood vessels on the way back up as the snot cork would not move! That expanding air had to go somewhere or do some damage, its better then two times I think it has happened when that compressed air building in the sinuses explodes through the flesh propelling all those tiny bones behind the nose into the brain!
Any one who reads this for heavens sake, if the water you surf, free dive or scuba dive in is below 22c, wear a hood for divers or suitable ear plugs for surfers only!
In Auz the way we drive puts our right ear near the window, so possibly earlier or by old age most drivers who drive with the window down in cool temps will have it to some degree in that ear!
Hope your dive turned out well.
