RT Journal Article SR Electronic T1 Back pain: medical evaluation and therapy JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 163 OP 168 VO 62 IS 3 A1 Daniel J. Mazanec YR 1995 UL http://www.ccjm.org/content/62/3/163.abstract AB SUMMARY Most patients with acute low back pain or sciatica improve with appropriate conservative therapy, and most require no immediate diagnostic studies beyond a careful history and examination. □ In patients with "red flags" for visceral, malignant, or infectious causes or possible cauda equina syndrome, a more aggressive evaluation is mandatory. □ In patients whose pain does not respond to initial management or who have chronic symptoms, diagnostic reevaluation is appropriate.
