A slipped disc is when a soft cushion of tissue between the bones in your spine pushes out. It’s painful if it presses on nerves. It usually gets better slowly with rest, gentle exercise and painkillers. You can have a slipped disc in any part of your spine, from your neck to your lower back. The lower back is one of the more common areas for slipped discs. Your spinal column is an intricate network of nerves and blood vessels. A slipped disc can place extra pressure on the nerves and muscles around it.
A slipped disc occurs when the outer ring becomes weak or torn and allows the inner portion to slip out. This can happen with age. Certain motions may also cause a slipped disc. A disc can slip out of place while you are twisting or turning to lift an object. Lifting a very large, heavy object can place great strain on the lower back, resulting in a slipped disc. If you have a very physically demanding job that requires a lot of lifting, you may be at increased risk for slipped discs.
