Childofchaos,
Sorry to hear that. My low back isn't in constant pain or I would have to make some kind of exception. Just when I move wrong and a nerve is pinched or vertebra grinds in a bad way (is there a good way?). I have had the imaging guided steroid shots a couple of times. They use a long needle and some kind of imaging (ultrasound?) to give 4 shots of cortisone and numbing medicine at the corners of whichever vertebra appears to be the pain center. That helps for a while.
