Pinched Nerve in Low Back

What is lumbar radiculopathy?: The most commonly affected levels for lumbar radiculopathy in the low back are between the L4-L5 (forth and fifth lumbar vertebrae) and between the L5-S1 (fifth lumbar vertebrae and base of the sacrum). Pressure on the nerves at these levels is usually felt in the buttock, down the back of the thigh and into the calf and/or foot. This condition is also called sciatica. Nerves in the middle lumbar area refer to the outside thigh and over the knee. Nerves in the upper lumbar spine can refer symptoms to the groin or inner thigh. Where the symptoms are felt depends on the nerve affected and its area of distribution.
