Slipped disc is most frequently used as an informal and misleading name for the medical condition known as spinal disc herniation .A ‘slipped’ (prolapsed) disc often causes severe lower back pain. The disc often presses on a nerve root which can cause pain and other symptoms in a leg. In most cases, the symptoms ease off gradually over several weeks. The usual advice is to do normal activities as much as possible. Painkillers may help. Physical treatments such as spinal manipulation may also help. Surgery may be an option if the symptoms persist.
