As a disc degenerates, the soft inner gel in the disc can leak back into the spinal canal. This is known as disc herniation, or herniated disc. Once inside the spinal canal, the herniated disc material then puts pressure on the nerve, causing pain to radiate down the nerve leading to sciatica or leg pain (from a herniated disc in the lumbar or lower back) or arm pain (from a herniated disc in the neck).
