A herniated (slipped) disk occurs when all or part of a disk is forced through a weakened part of the disk. This may place pressure on nearby nerves or the spinal cord.
Lumbar radiculopathy; Cervical radiculopathy; Herniated intervertebral disk; Prolapsed intervertebral disk; Slipped disk; Ruptured disk; Herniated nucleus pulposus
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 vertebra.
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.
With herniated disk:
A herniated disk is one cause of radiculopathy. This is any disease that affects the spinal nerve roots.
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.
The pain most often occurs on one side of the body.
With a slipped disk in your lower back, you may have sharp pain in one part of the leg, hip, or buttocks and numbness in other parts. You may also feel pain or numbness on the back of the calf or sole of the foot. The same leg may also feel weak.
With a slipped disk in your neck, you may have pain when moving your neck, deep pain near or over the shoulder blade, or pain that moves to the upper arm, forearm, and fingers. You can also have numbness along your shoulder, elbow, forearm, and fingers.
The pain often starts slowly. It may get worse:
After standing or sitting
When sneezing, coughing, or laughing
When bending backward or walking more than a few yards
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 often goes away or improves a lot over weeks to months.
Exams and Tests
A careful physical exam and history is almost always the first step. Depending on where you have symptoms, your doctor examines your neck, shoulder, arms, and hands, or your lower back, hips, legs, and feet.
Your doctor will check:
For numbness or loss of feeling
Your muscle reflexes, which may be slower or missing
Your muscle strength, which may be weaker
Your posture, or the way your spine curves
Your doctor may also ask you to:
Sit, stand, and walk. While you walk, your doctor may ask you to try walking on your toes and then your heels.
Bend forward, backward, and sideways
Move your neck forward, backward, and sideways
Raise your shoulders, elbow, wrist, and hand and check your strength during these tasks
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.
(EMG) may be done to determine the exact nerve root that is involved.
may be done to determine the size and location of disk herniation.
or will show where the herniated disk is pressing on the spinal canal.
may be done to rule out other causes of back or neck pain. However, it is not possible to diagnose a herniated disk by a spine x-ray alone.
The first treatment for a slipped disk is a short period of rest with medicines for the pain. This is followed by physical therapy. Most people who follow these treatments recover and return to normal activities. Some people will need to have more treatment. This may include steroid injections or surgery.
Medicines can help with your pain. Your doctor may prescribe any of the following:
- Nonsteroidal anti-inflammatory drugs (NSAIDs) for long-term pain control
- Narcotics if the pain is severe and does not respond to NSAIDs
- Medicines to calm the nerves
- Muscle relaxants to relieve back spasms
If you are overweight, diet and exercise are very important for improving back pain.
Physical therapy is important for nearly everyone with disk disease. Therapists will teach you how to properly lift, dress, walk, and perform other activities. They teach you how to strengthen muscles that help support the spine. You will also learn how to increase flexibility in your spine and legs.
Take care of your back at home:
- Reduce activity for the first few days. Slowly restart your usual activities.
- Avoid heavy lifting or twisting your back for the first 6 weeks after the pain starts.
- After 2 to 3 weeks, gradually start exercising again.
Steroid medicine 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.
Surgery may be an option if your symptoms do not go away with other treatments and time.
Diskectomy is surgery to remove all or part of a disk.
Discuss with your doctor which treatment options are best for you.
Most people improve with treatment. But you may have long-term 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.
In rare cases, the following problems can occur:
Long-term back pain or leg pain
Loss of movement or feeling in the legs or feet
Loss of bowel and bladder function
When to Contact a Medical Professional
Call your health care provider if:
You have severe back pain that does not go away
You have any numbness, loss of movement, weakness, or bowel or bladder changes
Being safe at work and play, using proper lifting techniques, and controlling weight may help prevent back injury.
Your health care provider may recommend a back brace to help support the spine. A brace can help prevent injuries in people who lift heavy objects at work. But using these devices too much can weaken the muscles that support your spine and make the problem worse.
