In fact I am fairly certain it is. I was sitting wondering about this crazy back issue and I remembered something. A while back we had a chiropractor office come to school and feed us lunch and do this free test thing on your spine. It was obviously to drum up business and the test was obviously nothing like an Mri. But they put these electrodes like things on you and spots that need attention show up yellow or red.I had three "red" areas. They said, of course, that I should make an appointment. I assured them that I would (liar liar pants on fire) Now I am wondering if I really should have. Anyone else had this free"test?"
