Sciatic Nerve and Sciatica

Description: Sciatica refers to symptoms arising from entrapment of lumbar spinal nerve roots. The symptoms are pain, tingling and numbness in the distribution of lumbar nerve roots - the buttocks, thigh, outer calf, foot and toes. Symptoms in sciatica typically extend to below the knee.
* The terms 'nerve root pain' or 'radicular pain' are also used for sciatica.
* Sciatica may occur together with non-specific low back pain. In this situation, the sciatica symptoms are usually the main problem.
