Diagnosis:

Sciatica is a condition of the lower back caused by pressure on and/or injury to the sciatic nerve, which can occur as a result of a herniated disc, spinal stenosis, or a number of other injuries to the lower spine. As the sciatic nerve is the largest in the human body, moving from the lumbar spine down the back of the legs, any injury to it can be debilitating. In those affected by sciatica, the sensation normally provided by the sciatic nerve is impeded, with pain and/or tingling that extends from the lower back to the back of one leg being the distinguishing symptom. The level of pain associated with sciatica can vary, but is often significant enough that affected individuals seek prompt treatment.
