Looks like I've got tinnitus, otherwise known as ringing in the ears. Mine sounds more like a constant high pitched set of frequencies, almost electric. For over twenty years, I've had a history of developing ear wax buildup and having it removed by an ENT. The last few years, I've been doing it myself using Debrox and the rubber bulb syringe with water. Tinnitus is something else. I'd say I first noticed it on February 22 this year, but not to the extent or severity of it as I have over the last few days.
The news on tinnitus is not good and it may very well be that my condition will not improve. There is a chance that over time it will get better, but from what I've read, if the damage is severe, it could be permanent. So protect your ears from loud noise!
