For the first time in my life, I was able to immediately see a correlation between stress and increased ringing. Received a certified letter for my Mom from insurance stating a hospital visit wasn't covered and after reading it twice, the ringing went in to overdrive.

For hearing aids, a co-worker went to Costco and was able to get a set for under 2K. This is not an advertisement, but he did a lot of research and has been pleased so far.

I have found nothing that helps and have just learned to live with it or tune it out for the last 23 years.
