A herniated (slipped) disk occurs when all or part of a disk in the spine is forced through a weakened part of the disk. This may place pressure on nearby nerves.

The bones (vertebrae) of the spinal column protect nerves that come out of the brain and travel down your back to form the spinal cord. Nerve roots are large nerves that branch out from the spinal cord and leave your spinal column between each vertebrae.
The spinal bones are separated by disks. These disks cushion the spinal column and put space between your vertebrae. The disks allow movement between the vertebrae, which lets you bend and reach.
Radiculopathy is any disease that affects the spinal nerve roots. A herniated disk is one cause of radiculopathy.
Slipped disks occur more often in middle-aged and older men, usually after strenuous activity. Other risk factors include conditions present at birth (congenital) that affect the size of the lumbar spinal canal.
Low back or neck pain can feel very different. It may feel like a mild tingling, dull ache, or a burning or pulsating pain. In some cases, the pain is severe enough that you are unable to move. You may also have numbness.
The pain most often occurs on one side of the body.
The pain often starts slowly. It may get worse:
You may also have weakness in certain muscles. Sometimes, you may not notice it until your doctor examines you. In other cases, you will notice that you have a hard time lifting your leg or arm, standing on your toes on one side, squeezing tightly with one of your hands, or other problems.
The pain, numbness, or weakness will often go away or improve a lot over a period of weeks to months.
A careful physical exam and history is almost always the first step. Depending on where you have symptoms, your doctor will examine your neck, shoulder, arms, and hands, or your lower back, hips, legs, and feet.
Your doctor will check:
Your doctor may also ask you to:
Leg pain that occurs when you sit down on an exam table and lift your leg straight up usually suggests a slipped disk in your lower back.
In another test, you will bend your head forward and to the sides while the health care provider puts slight downward pressure on the top of your head. Increased pain or numbness during this test is usually a sign of pressure on a nerve in your neck.
The first treatment for a slipped disk is a short period of rest with medications for the pain, followed by physical therapy. Most people who follow these treatments will recover and return to their normal activities. A small number of people will need to have more treatment, which may include steroid injections or surgery.
People who have a sudden herniated disk caused by injury (such as a car accident or lifting a very heavy object) will get nonsteroidal anti-inflammatory medications (NSAIDs) and narcotic painkillers if they have severe pain in the back and leg.
If you have back spasms, you will usually receive muscle relaxants. Rarely, steroids may be given either by pill or directly into the blood through an IV.
NSAIDs are used for long-term pain control, but narcotics may be given if the pain does not respond to anti-inflammatory drugs.
Diet and exercise are crucial to improving back pain in overweight patients.
Physical therapy is important for nearly everyone with disk disease. Therapists will tell you how to properly lift, dress, walk, and perform other activities. They will work on strengthening the muscles that help support the spine. You will also learn how to increase flexibility in your spine and legs.
You may want to reduce your activity for the first couple of days. Then, slowly restart your usual activities. Avoid heavy lifting or twisting your back for the first 6 weeks after the pain starts. After 2 - 3 weeks, gradually start exercising again.
See Taking care of your back at home for more about exercise and how to prevent your back pain from returning.
Steroid injections into the back in the area of the herniated disk may help control pain for several months. These injections reduce swelling around the disk and relieve many symptoms. Spinal injections are usually done in your doctor's office, using x-ray or fluoroscopy to find the area where the injection is needed.
Surgery may be an option for the few patients whose symptoms do not go away with other treatments and time.
See Diskectomy for more about how the surgery is done and who is most likely to benefit from it.
Ask your doctor which treatment options are best for you.
Most people will improve with treatment. However, you may have back pain even after treatment.
It may take several months to a year or more to go back to all of your activities without having pain or straining your back. People who work in jobs that involve heavy lifting or back strain may need to change their job activities to avoid injuring their back again.
Call your health care provider if:
Being safe at work and play, using proper lifting techniques, and controlling weight may help prevent back injury in some people.
Some health care providers recommend the use of back braces to help support the spine. Such braces can help prevent injuries in people who have to lift heavy objects at work. However, using these devices too much can weaken the abdominal and back muscles, making the problem worse.
