Well, I gave it a chance. After my first appointment with the chiropractor, my back didn't hurt. After the second (first follow up) appointment, my back didn't hurt. For all of two days. That was five days ago, and now it's been hurting quite badly, worse than it has in quite some time. I think I'll cancel the final appointment for the end of January. No point in wasting any more money on this failed experiment. Time to get me to a real doctor.
