Coming to the conclusion that some of our auditory systems are more vulnerable than others. Hence some of us get t and some don't. Whether that is vulnerability at the time of a sudden loud noise, a dose of certain drug, or if it is vulnerability that has been building for years due to stress etc, well that is unclear. Of course if tmj/cervical issues are impinging on the nerve etc, and there can be a fix. Well that does seem significant. My t was caused by local anesthetic, administered at the same time as a menstrual migraine and significant stress in my life. But if t hadn't happened then, I wonder if something else would have triggered it along the way. Interesting. Somehow it takes the pressure off of blaming ourselves or others for this condition, or forever trying to work out the factor/hundreds of factors that could have contributed towards it.
