Herniated discs often do not need to heal at all. That is because most minor and moderate herniated discs are not painful or problematic in any way. They merely exist. In fact, herniated discs are a common side effect of normal spinal aging.
A herniated disc occurs when the gel-like center of your disc ruptures out through a tear in the tough disc wall (annulus) (Fig. 1). The gel material is irritating to your spinal nerves, causing something like a chemical irritation. true herniated disc (also called a ruptured or slipped disc) occurs when the disc annulus cracks or ruptures, allowing the gel-filled center to squeeze out. Sometimes the herniation is so severe that a free fragment occurs, meaning a piece has broken completely free from the disc and is in the spinal canal.
