A herniated disc refers to a problem with one of the rubbery cushions (discs) between the individual bones (vertebrae) that stack up to make your spine.
A spinal disc is a little like a jelly donut, with a softer center encased within a tougher exterior. Sometimes called a slipped disc or a ruptured disc, a herniated disc occurs when some of the softer “jelly” pushes out through a crack in the tougher exterior.
A herniated disc can irritate nearby nerves and result in pain, numbness or weakness in an arm or leg. On the other hand, many people experience no symptoms from a herniated disc. Most people who have a herniated disc don’t need surgery to correct the problem.
You can have a herniated disc without knowing it — herniated discs sometimes show up on spinal images of people who have no symptoms of a disc problem. But some herniated discs can be painful. Most herniated discs occur in your lower back (lumbar spine), although they can also occur in your neck (cervical spine).

The most common signs and symptoms of a herniated disc are:
- Arm or leg pain. If your herniated disc is in your lower back, you’ll typically feel the most intense pain in your buttocks, thigh and calf. It may also involve part of the foot. If your herniated disc is in your neck, the pain will typically be most intense in the shoulder and arm. This pain may shoot into your arm or leg when you cough, sneeze or move your spine into certain positions.
- Numbness or tingling. People who have a herniated disc often experience numbness or tingling in the body part served by the affected nerves.
- Weakness. Muscles served by the affected nerves tend to weaken. This may cause you to stumble, or impair your ability to lift or hold items.
