ARRGH GO AWAY!
i like how when it goes away, it slowly creeps back.
I think this is why I always have background noise going on (fan while I sleep, TV On in the background, car radio)
I can understand how it feels. About 10 years ago my wife and I were counselors at a church camp, opened up a seldom-used building, turned on a big fan. Short story I got really hot, put my face in the fan with my mouth open. About 4-5 hours later I started getting the worst sinus infection which spread to my ears. 3 weeks of pure misery, like they were full of water.
I was working phone tech support for an ISP then and had to take a week leave as I could not hear the person on the other end of the phone clearly enough.
When it subsided I was left with the most horrible ringing and squealing in my ears. I'm a full-grown guy but I'll admit several times when I was by myself I broke down crying thinking of what if it doesn't go away. Went to a hearing analysis unit at the hospital for testing, nothing found at that time.
After about 2-3 years the ringing and squealing in the right ear subsided to a light hiss, then disappeared. The left side after about 3-4 years went down to a very light hiss and some days it still is present. I have largely learned to ignore it, but no hearing loss in the left ear. Right ear 10% loss.
Point of this post? Just to let you know I understand how it can feel and it can be related to a lot of things, blood pressure/sodium intake, caffeine, even stress. I learned a lot about it back then. Fortunately my ears are 90-95% back to the way they were beforehand.
It can be very miserable.
