Get to a good chiro or a massage therapist or a combo of the two. I really believe in Chiro for myself, and we use them for horses, and I can tell you that when my horse gets adjusted you can see relief in her eyes. She loves her chiro like no one else, even more than the guy who feeds her. My chiro uses massage, physical therapy and adjustments to keep my back good. It's a combo.
MD's will give you good drugs. And that's about it. And if you have lower back pain like mine used to be, the drugs will make you feel great and not do a lick of good for your back pain.
