@rwinney and others. Also, be aware that in his "Life after pain" book, Dr. Jonathan Kuttner has a "Phoenix program" and a "master your pain system" program that uses mind -body teachings, etc. to talk about getting out of pain / retraining your pain system. It is beyond the book and I believe somewhat expensive - but you'll need to check their pricing if interested at: https://lifeafterpain.com/info/products/ if things don't work out with your other pain clinic and pursuits.

Someone mentioned there are biochemical changes in the brain and nervous system that potentiate the pain. That is correct and known. It is not "all in your head" There are numerous scholarly articles about this is you search "scholarly articles and pain sensitization". Lot's of biochemical and medical terminology but basically the nervous systems gets excited (here is one: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2750819/). You will presumably need to partly retrain the pain system (Dr. Kuttner talks about this malfunction a lot and does have those programs above, that may help retrain the pain system) and he also has various videos (and stories of success and peoples struggles) out on the web about pain (and relief). Good luck.
