Having had T for so long, and knowing its ups and downs, I was never prepared for what began last October. Suddenly it became a level so loud there's no getting away from it. There seems to be no accustoming myself to it and it doesn't ever change. I visited a very famous doctor at NYU Langone, put me through a cerebral angiogram thinking I had a fistula. Terrifying, full of radiation and risks, and it was all for nothing when they got in my brain they saw nothing. Now I have no where to go with this noise. Sleep is so difficult, and my life is totally upside down. I will try the training sound therapy if anyone suggests , but would deeply appreciate help. What was in one ear is now both with different noises, one a loud vibrating engine, The other a high pitched squeal. What is happening.
