Ditto here, except mine goes back to 2006 when I had a dental procedure known as onlays or crowns on two of my molars. Knew immediately something was wrong the second he placed them on the living tooth stubs – I’ve had ringing ever since, felt in my head, not the ears; Lost track of everything I’ve tried along the way – craniosacral, accupuncture, binaural beats, herbal/supplements, trigger point, etc. It was interesting I found some articles written by Dr. Gabriel Cousens ~2018-19 regarding Piezoelectricity, and it seemed to come close to the mark as a possible cause for Tinnitus, where matter such as crystals, ceramics, or biological bone accumulate an electrical charge in response to applied stress. Thinking in terms of the old “crystal radios” that were a hobby project at one time. And then, lo and behold, Dr. Cousens became a guest on Alfacast a year or so later! I’ve only had a few brief moments of it not being there (perhaps there is a reason for that) and man those moments were nice, so if anyone does not experience this frequency jam thank your stars!
