I absolutely do, in highschool I had debilitating back pain, like miss school and work type stuff. Which means I couldn't get out of bed. Went to doctors that recommended back operations, and had several different doctors say the same thing.
Then I went to a chiropractor. After a few months of adjustments, and following his workout regimen, I haven't had the problems since.
Now, once I sat in a meeting where the chiropractor claimed (and I'm not exaggerating) he could cure cancer. Would only allow you to come to the meeting with your spouse, then proceded to hammer us as if we were buying a time share. It was pretty out there...
