Once the major (though exceedingly rare) problems have been ruled out, the best course of action is to start learning to live with it.
It’s not what anyone wants to hear, but it’s the pragmatic approach that works best from everything I’ve seen.
The people who become involved in tinnitus forums, support groups, and chasing experimental treatments think they’re helping themselves but they’re really only bringing it to top of mind over and over again.
It feels frustrating to give up and disconnect from all things tinnitus related on th internet, but disconnecting is exactly what helps with the process of letting it fall into the background of your life. Constantly bringing it to the foreground and reading about it only makes it worse.
