I have a constant grumbling backache but when I lean to the right I have excruciating pain. I also have numbness in my right glute.

I had x-rays done a couple years back. Recently I had an MRI that was "normal" but my PCP suggested the images weren't very good. However my insurance won't pay for a repeat MRI.

I have seen a physiotherapist with little to show for it. I'm worried about seeing chiropractor after reading about Vertebral Artery Dissection after spinal manipulations.

Have others had good experiences with chiropractors?
