Hello @neuropathy, I see that you have been a member since 2019 but this is your first post so I want to welcome you to Connect. It can be very difficult when you are feeling all alone and trying to figure out a diagnosis. I am sure that you are definitely not alone. Here are a couple Connect discussions on tinnitus you might be interested in:

--- On pulsatile tinnitus, https://connect.mayoclinic.org/discussion/pulsatile-tinnitus-1/
--- On tinnitus control, https://connect.mayoclinic.org/discussion/tinnitus-control.

Have you thought about seeking help at a teaching hospital or major health facility like Mayo Clinic?
