Androgens always cause my ears to produce ridiculous amounts of ear wax and inner ear fluid. I'm glad I'm not alone on that. Not that I would wish it on anyone.
The tube that allows fluid to drain out of your middle ear (behind your ear drum) is in it's own little chamber with all your hearing apparatus. So sometimes if I get a stuffy nose (hay fever or sinus infection) one or even both ears tubes (auditory tubes) will swell shut and my middle ear fills with fluid. (feels like having water in your ears)
My ENT gave me a Rx for pseudoephedrine (Sudafed) and an antibiotic (amoxicillin) to prevent infection and she said if that didn't work, they could insert tubes that dissolve on their own but allow the fluid to drain out the outer ear instead of down to the throat like it normally does.
She said if too much fluid builds up, it can actually damage the ears. It really sucks.
But for what it's worth, the pseudoephedrine really helped me. Just a thought.
Just an added note: I'm a certified diver and when you go to depth, your ears equalize the air pressure in that middle ear chamber. But when you come back up to the surface, that air expands as you ascend and can rupture your eardrum if it can't escape through that auditory tube. If you have a cold or runny nose, that tube can get closed off. In the classroom, we were taught that pseudoephedrine is THE medicine to prevent that from happening (along with just not diving at all).
