Tinnitus (ringing or roaring in the ears) is one of the few things I can’t reliably treat with acupuncture. It can be mildly irritating or absolutely maddening, depending on the frequency, volume, and pitch.
Here’s a use-at-home method that just requires your hands. I can’t test it personally since I don’t suffer from tinnitus, but two of my friends who do reported this gave them temporary relief. I suspect it has to do with the impact affecting the vagus nerve. Anyway, here’s the video: Good luck!
