It's rather amazing that the mind-body / mind-body-metaphysical connection to various disorders, is only fairly recently gaining serious traction. I believe Sarno's seminal book, The Divided Mind, The Epidemic of Mindbody Disorders, only came out in 2006. I do agree that the complementary approach between traditional and non-traditional makes sense. I read a fascinating article in the NYT recently where practitioners are reversing the process--not treating emotional trauma to relieve the physical pain but using new methods to treat the body to get it to release the stored trauma and thus treat the emotional as an after effect of how they treat the physical. https://www.nytimes.com/2023/05/18/magazine/somatic-therapy.html?unlocked_article_code=8J3hQ50kZFj8MceKLJw8xw6r4dx1OVfCdqQD1Lbyx4Ad53SMAT4f6l8_VPmw2CbDtTFwqELDZEL8eZPbedtmqdj2rz2AU0xGRUQbOQXInmgco2ebOnCdR0o7IxNtmdGhFpHmr_am6TZ9jhzmlUMHahkeE1RQwqtolXdZ44fDv5jPuriT1Efw4bxZ6LwaXwMn8H4OjL1GDG4hL4D395b2i52BVtrUFNJ9Wlmptoi-sMZiU4JfJIa_-eXiHF5c3-bYwPCCM0Cg6STNvofW09W00x0MV05Q6Jv1UNAgVLS0jDoaDkfbnfJzuSi93OGgaNCDE8oXdGuGgkPhkg&smid=nytcore-android-share That is an unlocked link for anyone without a subscription. It's also relevant to note that the few practioners who suggest complementary approaches get shunned by devotees to the new ideas.
I have my own personal experience with the confluence of medical and metaphysical. I was properly diagnosed with idiopathic truncal dystonia and after several years I even resorted to brain surgery and later determined through a metaphysical experience that my condition was at least largely and possibly entirely psychosomatic. https://medium.com/know-thyself-heal-thyself/my-personal-experience-with-idiopathic-truncal-dystonia-dd10f0a13a25
