I experienced this tonight, hence my Google search which led me here. My tinnitus has been growing in perceived volume the past few weeks. I am unsure of the cause, but I can confirm I have been consuming a lot of coffee lately (at least 3-4 large mugs daily). I also have some TMJ problems which I am curious if they could be contributing as sometimes the popping of my jaw makes my ears ring. I have been learning to not panic or feel alarmed when the symptoms appear strong as I know my doctor's can't do anything about it. I just want to know I'm ignoring tinnitus and not a potential brain tumor or other malady which otherwise would need to be investigated.
