A friend of mine had this condition. He had hearing loss and the sensation of his ear being plugged. He had surgery to remove the bone growth.@Swipter you might have:
External auditory exostoses. Also called surfer's ear, this type of exostosis is caused by chronic cold water exposure. It's a buildup of bone growth in the external ear canal. There are usually no symptoms but people with surfer's ear may have hearing loss, ear infections, ear drainage, and earwax impaction.
You don't have to be a surfer to get it, but usually repeated exposure to cold air/water is involved. I don't surf frequently enough to have this, but know many who do, and some who have had the surgery to correct it. It sounds nasty, essentially boring out the ear canal.
I've had tinnitus for decades and my ears are ringing as I type this. One trigger is riding in a car for long periods. The constant road noise sets it off and it lasts for hours.
