I googled around and found out about "SSHL" SSHL stands for "Sudden SensoryNeural Hearing Loss" and it can come on in a few different forms, but for me it happened over a couple hours while working at the computer, like I am now. When it finally hit full force, there was a HUGE increase of my regular tinnutus, but in just one ear. I could not hear out of that ear, tinnitus or not. There was dizzyness and nausea, though mild. It lasted for three or four hours, and all I could do was sit in my recliner and bear it. I thought it might be a stroke, and in fact it is called "an ear stroke". When I did turn the TV on, the sound was like it was coming from a poor quality tinny sounding hearing aid speaker that was right in my ear - perception was very skewed, obviously! Then, after those four hours, things started to return to normal, over the next two hours. I guess I was lucky - many with SSHL have those symptoms permanently. I don't know how I could stand it - normally, for many years now, I have tinnitus pretty bad but this episode was out of hand, like a jet engine in my living room. It overshadowed all other sounds too, even tho my other ear was normal I could not hear anything but the "jet engine". My googling suggests it could be from a bug - virus, etc., or some sort of nerve damage in the aural nerve, or, my favorite - it could be related to "sensory processing overload" and fatigue and so on. There is a phenomenon called "recruitment" that is interesting too, and explains why some sounds can be percieved as very loud. Anyone else have an experience like this? I think it would be more common in our group, since we have lots of "sensory processing pain disorder" victims here.
