Low back pain is the second most common cause of doctor visits in the U.S. and is the most common cause of disability. Up to 90% of the population will experience back pain during their lives. Studies show that, at any given time, up to 20% of the population is... Differential Diagnosis ... Workup and Diagnosis ... Treatment
