April 4, 2018 tinnitus was reactivated by a machine used by a physiotherapist called a thumper. The vibrations started the ringing in my ears again. I used sound imitators for the ringing,whooshing sound(crickets) and the pulsing (heart beat) to help me sleep. You can find sounds that help on youtube. I then started trying different relaxant and sleeping medication. I finally found that a combination of amitryptiline and Immovane are working for me to sleep a good nights sleep. It is only starting to ease now (i.e. end of July) after 2 weeks of this combination plus the sounds. I also meditate and sought counselling, read the bible, prayed and had many pray for me. In counselling I was told either to try to distract myself from the worrying or to think it through whichever works.
Hopefully this helps you.
