A spinal disk is a little like a jelly donut, with a softer center encased within a tougher exterior. Sometimes called a slipped disk or a ruptured disk, a herniated disk occurs when some of the softer “jelly” pushes out through a crack in the tougher exterior.
Disk herniation is most often the result of a gradual, aging-related wear and tear called disk degeneration. As you age, your spinal disks lose some of their water content. That makes them less flexible and more prone to tearing or rupturing with even a minor strain or twist.
Sometimes, using your back muscles instead of your leg and thigh muscles to lift large, heavy objects can lead to a herniated disk, as can twisting and turning while lifting. Rarely, a traumatic event such as a fall or a blow to the back can cause a herniated disk.
Herniated disks sometimes show up on spinal images of people who have no symptoms of a disk problem. But some herniated disks can be painful. The most common signs and symptoms of a herniated disk are:
- Arm or leg pain. If your herniated disk 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 disk 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 disk 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.
- Over-the-counter pain medications
- Nerve pain medications.
- Muscle relaxers.
- Cortisone injections.
A very small number of people with herniated disks eventually need surgery. Your doctor may suggest surgery if conservative treatments fail to improve your symptoms after six weeks, especially if you continue to experience:
- Numbness or weakness
- Difficulty standing or walking
- Loss of bladder or bowel control
In many cases, surgeons can remove just the protruding portion of the disk. Rarely, however, the entire disk must be removed. In these cases, the vertebrae may need to be fused together with metal hardware to provide spinal stability. Rarely, your surgeon may suggest the implantation of an artificial disk.
- Take pain relievers.
- Use heat or cold. Initially, cold packs can be used to relieve pain and inflammation. After a few days, you may switch to gentle heat to give relief and comfort.
- Avoid too much bed rest.
Pain affects more than just your physical well-being. If you have to deal with recurring herniated disks or other back problems, your psychological and emotional health also are vulnerable. Exercising the trunk muscles helps stabilize and strengthen the spine muscles. Good posture reduces the pressure on your spine and disks. Keep your back straight and aligned, particularly when sitting for long periods. Lift heavy objects properly, making your legs — not your back — do most of the work.
