背痛免吃藥免手術

For the upper back, sit in a chair and give yourself a hug. Do this by grabbing your opposite shoulder with each hand. Holding your shoulders, look down. Again, hold the stretch for four deep breaths. When you do this, one arm will be above the other. Once you complete the stretch, switch so that the other arm is on top and repeat the stretch.

原文出處

上背會痛的人可以試試，坐在椅子上然後抱住你自己。就是用雙手抓著相對
的肩，頭向下看，做四次深呼吸，之後換手，再做四次深呼吸。就這麼簡單
可以消除背痛。

或者其中提到吃 B complex 或退黑激素可能都有效。

試試看吧！
