Conservative treatments for lumbar radicular pain.

Lumbar radicular pain is a frequent medical pathology and represents a significant burden on society. The diagnosis of sciatica is largely clinical, in the setting of a combination of radicular pain and neurologic deficits (motor, reflexes, and/or sensation) or a positive straight leg raise test. Imaging is generally not necessary for sciatica, except in the presence of warning signs or in the setting of persisting or worsening pain. The recommended first-line treatment has not yet been clearly established. The choice of a conservative treatment approach combined with simple analgesics in the initial stages seems to be reasonable. A detailed discussion with the patient is important to explain the fact that surgery may only be necessary in the event of pain persisting in excess of 3 months or because of the development or worsening of a neurologic deficit. More high quality studies are clearly required to assist the medical practitioner in knowing how best to treat this group of patients.
