The usual presenting complaint is acute or chronic intermittent LBP with or without sciatica, which is radiating pain in a dermatomal distribution and classically described as a burning, stabbing, or electric sensation, sometimes accompanied with paresthesia. Central disc herniations or herniation that have migrated can each result in a mixed clinical picture or, alternately, signs of stenosis may predominate. The mechanism of pain is mutifactorial, involving mechanical stimulation of the nerve endings in the outer annulus, direct compression on the posterior longitudinal ligament, dura, or nerve root, and/or the chemical inflammatory cascade induced by the exposed nucleus pulposus or annulus fibrosis.The classic straight leg raising (SLR) test or Lasegue test is thought to be a useful clinical test to demonstrate an inflammatory compressive process across single or multiple spinal nerve roots.
