A slipped disc is when soft cushion tissue between the bones in your spine pushes out. A slipped disc can be painful if it presses on nerves. The term “Slipped Disc” is often used to describe a number of different conditions where the soft cushion tissue, intervertebral disc, pushes against a nerve as it exits the spine. Whether this be in the neck or lower back it can cause intense pain both where the nerve goes to, as in sciatic pain, as well as where the disc is injured.
