Googled the following and I your post came up: "when i bite down the ringinging gets louder". I didn't realize that this was a problem until I asked another person if they shared the same reality as I and they said no. Then I started imagining life without the ringing. Worst mistake I have ever made because I didn't know that there was no cure for this ringing. I'm curious to know what causes and/or cures it, but like the little boy on the tootsie roll commercial, I guess "the world may never know". I do remember receiving a series of terrible migraine headaches before becoming aware of this ringing in my right ear. Although my left ear is ring free, one morning I was awakened by ringing in my left ear also. It lasted for a few hours. During those hours I had to learn contentment fast or else go into a frenzy. I don't even remember when it went away; I just know that my left ear doesn't ring now. In my right ear it just keeps ringing and never stops. If I think about it to long, I start to get claustrophobic, and I have to do something to take my mind off of it. I strongly believe it has something to do with pressure, sinuses, and/or blood vessels. But I am nothing close to a Doctor.
A change in tinnitus with a change in jaw position or other movements seems pretty common. If you Google "tinnitus jaw movement" you will see lots of examples. I suppose the change when you apply pressure to different spots is something similar. I doubt it has anything to do with the actual cause of the tinnitus (but I'm not an expert).
I used to get a momentary increase in my tinnitus when moving my eyes sideways or sometimes upward.
Thanks, RadioAstronomyObserver. I took your advice and researched a little about Tinnitus, and it sounds as if it matches up. I've been paying more attention to things that affect the ringing in some way, and discovered that when I put pressure on the left side of my head above my ear, the ringing gets louder in my left ear, and when I put pressure on the right side, the ringing gets louder in my right ear. I guess this is in the same vein as when I said it gets worse when I bite down hard.
Does this mean anything? Is it possible the ringing is pressure related?
Got the same thing and it's surprising that you give the same example I give everyone else who asks. Unfortunately I have no information but I can say that when my heart rate drops It becomes louder. I also want to say when my BP drops but I'm still not sure about that yet. There is a tone difference at times but I have yet to correlate this to a specific thing. I also had a strange loud ring while having a heart attack which I'll assume at this time was related to an extremely low BP but don't necessarily want to go through it again to confirm this ;-)
Either case, the ringing is called -Tinnitus-. there are many references here if you want to look through the archives and I'm sure someone else will speak up with more information here.
