Every Man is a Builder of a Temple called His Body. – Henry David Thoreau Lower back pain has a long history in my life. Over the years I got used to a sensation of stinging pain at the back of my pelvis to one side when I came out of a standing forward bend, twist, or when standing up after a long period of sitting. Pretty quickly I figured out its origin could be traced back to the sacrum, this large triangular bone at the base of the spine, which provides the gravitational center of our body around which we move, twist and turn.
