In my case, my tailbone pain didn't feel as though a vertebrae was out of place (like it has in my mid/upper back and neck). Plus, I was seeing a chiropractor at the time who confirmed my tailbone was not out of alignment. Mine was a different kind of tailbone pain.... not made worse or better by stretching, chiro adjustments, or turning/bending a specific way. It was just an ever-present pain, 24/7, for almost a year.
