Sciatica

Sciatica is nerve pain resulting from irritation of the sciatic nerve. The pain of sciatica is typically felt from the low back to behind the thigh and radiating down below the knee. The sciatic nerve is the largest nerve in the body and begins from nerve roots in the lumbar spinal cord in the low back and extends through the buttock area to send nerve endings down the lower limb. Sciatica is different from other forms of low back pain because there are 2 sciatic nerves, and the pain is usually on 1 side.

Causes:

Irritation of the nerve from adjacent bone
Tumors
Internal bleeding
Piriformis syndrome (a pain disorder involving the narrow piriformis muscle in the buttocks)
Slipped disk
Degenerative disk disease
Spinal stenosis
Pelvic injury or fracture.

Symptoms:

Pain
A burning sensation
Numbness
Tingling radiating from the lower back and upper buttock down the back of the thigh to the back of the leg
