  3. Symptoms
    1. Region: Low Back Pain
    2. Radiation: posterior buttock or postero-lateral thigh
  4. Diagnosis: Sciatica as a predictor for Lumbar Disc Disease
    1. Overall
      1. Only 4% of Sciatica is Lumbar Disc Disease
      2. Patients with symptomatic Lumbar Disc Herniation have Sciatica in 99% of cases
    2. Findings that increase Specificity of Sciatica for Lumbar Disc Disease
      1. Pain worse in the leg than the back
      2. Pain or numbness follows a typical dermatomal pattern
      3. Pain worse with Valsalva Maneuver (e.g. coughing or sneezing)
    3. Findings suggesting diagnosis other than Lumbar Disc Herniation

Sciatica (C0036396)

Definition (CHV) lower back pain radiating to the buttocks

Definition (MEDLINEPLUS)

Sciatica is a symptom of a problem with the sciatic nerve, the largest nerve in the body. It controls muscles in the back of your knee and lower leg and provides feeling to the back of your thigh, part of your lower leg, and the sole of your foot. When you have sciatica, you have pain, weakness, numbness, or tingling. It can start in the lower back and extend down your leg to your calf, foot, or even your toes. It's usually on only one side of your body.

Causes of sciatica include

In many cases no cause can be found.

Sometimes sciatica goes away on its own. Treatment, if needed, depends on the cause of the problem. It may include exercises, medicines, and surgery.

Definition (CSP) syndrome characterized by pain radiating from the back into the buttock and into the lower extremity along its posterior or lateral aspect, and most commonly caused by protrusion of a low lumbar intervertebral disk; also used to refer to pain anywhere along the course of the sciatic nerve.
Definition (MSH) A condition characterized by pain radiating from the back into the buttock and posterior/lateral aspects of the leg. Sciatica may be a manifestation of SCIATIC NEUROPATHY; RADICULOPATHY (involving the SPINAL NERVE ROOTS; L4, L5, S1, or S2, often associated with INTERVERTEBRAL DISK DISPLACEMENT); or lesions of the CAUDA EQUINA.
