What is slipped disc?

Our back is made up of small bones piled up one and other with intervening soft cushions known as intervertebral discs or discs for short. These discs are soft structures with balloon like tendencies, i.e. they are tense and pressurized.When the disc (balloon) ruptures the contents go out of place and in the process cause back pain or pain in the legs (or in the arms and hands in case of neck problems) if it happens to irritate or cause pressure on nerves that pass nearby it.
