There is a $10.00 book called “life after pain” by Dr. Jonathan Kuttner. He discusses pain sensitization and also has some online courses where you can retrain your pain system. It works for many.

One more question: have you tried the enzymes nattokinase and serrapeptidase? They may help scar tissue remodel which can cut down on nerve compression which is often the cause of pain. Along with vitamin c, quercetin, resveratrol and stretching and exercise I got rid of a lot of myofascial pain thanks to the package of supplements- but especially the two enzymes. Those are taken on an empty stomach.
