I think mine was caused by an extreme high fever when I was young. It caused my ears to close a bit.
Having tubes put in every six months or so (would naturally fall out) was kind of a pain because when I was young they would have to do it in the operating room under general anesthetics. When I got older they didn't have to put me under but use local anesthetic, but still in the operating room. Finally a different doctor could do it in his facilities he had in his office.
I really hated taking medicine because I was worried about tolerance and other effects of taking antibiotics all the time. Once I was old enough to know more, when I had an ear infection I chose not to take antibiotics if the pain wasn't too severe.
Now I'm fine, but I think I lost a bit of hearing in my left ear. I also had to have skin grafted onto my right ear drum and there is a lot of scarring on my ear drums as well as scar tissue from the grafting surgery.
My left ear particularily gets plugged up whenever I get a cold. I don't want to get tubes again so I just wait it out. One doctor also recommend me to plug my nose and blow hard to force air out of the ears. It hurts, but it helps a bit. Sometimes it happens naturally when I blow my nose.
I rarely go swimming, but when I do I' always worried about getting an ear infection.
I hope Alex can have fewer problems and with Doc's suggestions, find a quick and easy solution.
