with lower back pain, you might oughta get an MRI done so you'll know for sure.. Chiropractors are ok for some stuff, but they can cause quite a few issues, themselves.. I have a friend who had shards of neck bone jabbed into his spinal cord by a chiropractor, requiring extensive neck surgery.. I'd kinda love to go to a Chiropractor now and have him try to pop my neck with a titanium plate screwed to it - although that would probably totally wreck my neck..
Friendship is like peeing your pants.. Everybody can see it, but only you can feel the warmth..
