I know that you said that you do not want to go to a chiropractor, but I began seeing one a few weeks ago and my back is SOOO much better than it has been in years. He does adjustments only if really needed, but focuses more on the actual mechanics and muscles and helps you to learn about the underlying conditions that cause your pain.
If you are interested, his name is Dr. Eric Lukosus, and his office is at Illinois Spinal and Sports Rehabilitation on Rte 59 in south Naperville. It's about a 30 min drive for me, but it's SOO worth it and I can't believe how effective his guidance and treatments have been. http://www.spinalandsportsrehab.com/
