Did the audiologist say you have any hearing impairment. If not, you need to forget about it. I have tinnitus too. The best thing to do is not focus on it and it goes away. As long as you do not have hearing loss you will be fine. Sleep with a fan. It drowns it all out.
there is a drug called serc 16 i know this is prescribed for vertigo, inner ear infections and tinnittus
