A good chiro helped me when the "real" doctor told me there was nothing he could do for me. The sudden, excrutiating muscle spasms in my upper back, a result of a race crash, had plagued me for more than a year, and were getting so bad that it hurt to breathe, and I couldn't turn my head. A chiropractor, who had been recommended highly, eliminated them completely. Granted, a lot of chiropractors are quacks who claim they can cure the flu by aligning your body. But a good one is worth his weight in painkillers.
