Happy Weekend,
I was doing some searches and came along a site about medical testing. This particular test is for people with back pain. I am NOT advocating you do this. I am suggesting this might need some more investigation. For those of us who have tried it all, this MIGHT be a solution (or not).
This is the link:

You might have to copy and paste.
Good luck and let me know if this looks viable for you.....
