The last time I visited a chiropractor was in 1984. I'd developed minor back spasms following a cross country race. Tom "Mac" McMurray, my coach at Glendale (Calif.) Community College, suggested I see a chiropractor. Mac had suffered lower back pain from sciatica. After dozens of failed remedies, he'd finally hit pay dirt with a chiropractic adjustment. His sciatica was cured.The first thing my 1984 chiropractor did was take an X-ray of my spine. Then he studied the X-ray, frowned, and said, "If you keep running, you risk never walking again."
