Pinched nerves or “radiculopathies” are a common complication of disc herniations or spinal stenosis in the cervical and lumbar spines. A disc herniation in the cervical spine can cause arm pain, while a disc herniation in the lumbar spine can cause leg pain or sciatica. Nerves can also be pinched or compressed peripherally in the musculature of the neck, low back or buttocks and cause similar symptoms that disc herniations or stenosis cause. If you have arm or leg pain you need a thorough examination to determine where and from what the nerve is being pinched.
