Interesting.
I also had an appliance made thinking my issues might be TMJ related. I wore the appliance almost constantly for about twelve weeks with no change.

I had electro-stimulation on my brain for a few months with no change.
Also interesting that you mention traumatic experience because I had a home invasion robbery a few years before Covid. I thought I was recovered from that trauma, but it seems Covid may have re-started fight or flight response.

I have honestly had hundred (yes hundreds!) of appointments over the last two years seeking answers. So far, no improvement and the conditions seem to be slowly progressing.
I guess other than the patches You find helpful, I have already tried many of the therapies you mention...acupuncture, chiropractic, yoga and meditation, sound therapy...the list goes on and on.
The key to my maladies is yet to be found.
