A freind told me this years ago and it works. Lay on the floor with your butt against the front feet of a chair, your legs bent at the knees are to lay across the seat. Lie very still for 20 minutes. It somehow seems to re-align your back. Now I am 82 and cannot lie on the floor(rather I couldn't get up if I did) but put a box on the bed, covered with a pillow. It still works!
