I observed that when I have severe back pain I take a shower at night and my mind and boy become so relaxed there will be no pain. This happened at least 4 times in last one month and then I can sit for any long time that night. Isnt this a good sign of TMS ? During the morning I can hardly sit for 10 mins. My pain returns again once I wake up. I think I have to relax my mind through mindfulness and living in present moment.
