Lumbar Radiculopathy (Sciatica)
In the lumbar and sacral regions of the back, several specific nerve roots unite to form the sciatic nerve, a large, thick nerve going out of the pelvis below the sacrum and down both legs. Irritation or pressure to the nerves in the lower back causes a sharp, burning shooting type of pain called sciatica. The shooting pains begin in the buttocks and run down the back of the thigh and the inside of the leg to the foot. The pressure on the nerve tissue can lead to tingling, numbness, and weakness in the legs. If the pressure on the nerve root is not relieved, the leg muscles will eventually waste away.
