If I am well understood, one of the most poweful sources of chronic pain (TMS) is self-punishment (or self-harm). That is the result of our divided mind: we are factory-equipped with such a device! "I love desperately my young daughter. She brought light and hapiness to my life but.... simultaneous I am very angry with her, enraged in fact, furious, because she has become addicted to drugs and alcohol. I have spend all my (modest) fortune in her rehab treatment, with no success. I am desperate and ruined. Frankly I desire the death of my beloved young daugther. It will end my (our) extremely suffering. I love my daughter, but I hate my daughter. I am fighting against me". No doubt: the perfect candidate for having chronic (back) pain !!! Psychological pain is the "peacekeeping force" that our protecting brain will send us in order to avoid not only depression but also autodestruction (suicide), since the main task of the brain is life preservation. All the best !
