Oh dear, it breaks my heart to read about your pain. Almost unbelievable. Do you use topicals in your pain area? Perhaps even cannabis topicals, balms, or ointments. It is interesting that you find biofeedback training helpful. Several years ago, I was rear-ended on the freeway. The recovery was pretty long and I had to get back to work. I was taught how to use biofeedback. It worked. When I packed to fly out on Mondays, I always included my biofeedback tapes. I think what actually happens is similar to mindfulness. It does take time and practice.

The last time I used it was the evening I fell down the mountain. In the ambulance, they told me I could not have any more pain meds as the paramedic wasn't authorized to give me more with such a high BP. I told him, "Give me five minutes and don't talk." He was so amazed that I could lower my BP by practicing biofeedback right there in the vehicle.

Would you be willing to try Mindfulness?
Be safe and protected from inner and outer harm.
