Thank you. Chiropractic can certainly be effective, but in this case he needs surgery. The disk has degraded to the point that it is nearly bone-on-bone, and what little is left is bulging into his spinal cord. Chiropractic can't do anything to help in his case.
Sadly no, the injury is from his youth. He doesn't qualify for any work-related benefits to treat it. He is loathe to seek government assistance. And he refuses to put his fellow officers at risk because his legs fail at a critical moment.
I am grateful for your prayers, friend.
