I kinda ask myself the same.. Its been shed so much light on the brain. But to my understandings it is well known that T can have a lot of causes, and one or more of them involves the brain.
I wish there was a clinic around in my area that spesialized in T and were able to start looking at the outer ear, and work its way inwards to rule out any causes of this mechanical part.
My ENT simply told me that my eardrum doesnt look perforated, and my hearing is better than average.
He also said that half of the population has T, so just deal with it!
At that time, I felt I was left to die.
Im so happy for this forum
