PAIN RELIEF TODAY AND FOREVER
The term sciatica describes the symptoms of leg pain—and possibly tingling, numbness, or weakness—that originate in the lower back and travel through the buttock and down the large sciatic nerve in the back of each leg.
The Sciatic Nerve and Sciatica
Sciatica symptoms occur when the large sciatic nerve is irritated or compressed at or near its point of origin.
The sciatic nerve starts in the lower back, typically at lumbar segment 3 (L3).
At each level of the lower spine a nerve root exits from the inside of the spinal canal, and each of these respective nerve roots then come together to form the large sciatic nerve.
The sciatic nerve runs from the lower back, through the buttock, and down the back of each leg.
Portions of the sciatic nerve then branch out in each leg to innervate certain parts of the leg—the thigh, calf, foot, and toes.
