Sciatica is a common impingement syndrome
The sciatic nerve is the largest in the human body- running from the lower back down the back of each leg. Because of its size and location, the sciatic nerve is prone to injury and pressure from a variety of conditions, the most common of which are:
- Disc herniation
- Piriformis syndrome
- Spinal misalignment
Symptoms are usually experienced as cramp-like irritation, numbing in the butt and the legs, and pain ranging from dull to sharp and shooting which can go right through to the lower extremities.
