A herniated disk refers to a problem with one of the rubbery cushions (disks) between the individual bones (vertebrae) that stack up to make your spine.
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.
A herniated disk 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 disk. Most people who have a herniated disk don't need surgery to correct the problem.
You can have a herniated disk without knowing it — 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. Most herniated disks 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 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.
WHEN TO SEE A DOCTOR
Seek medical attention if your neck or back pain travels down your arm or leg, or if it's accompanied by numbness, tingling or weakness.
CAUSES
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.
Most people can't pinpoint the exact cause of their herniated disk. 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.
FACTORS THAT INCREASE YOUR RISK OF A HERNIATED DISC MAY INCLUDE:
Weight. Excess body weight causes extra stress on the disks in your lower back.
Occupation. People with physically demanding jobs have a greater risk of back problems. Repetitive lifting, pulling, pushing, bending sideways and twisting also may increase your risk of a herniated disk.
Genetics. Some people inherit a predisposition to developing a herniated disk.
COMPLICATIOS
Your spinal cord doesn't extend into the lower portion of your spinal canal. Just below your waist, the spinal cord separates into a group of long nerve roots (cauda equina) that resemble a horse's tail. Rarely, disk herniation can compress the entire cauda equina. Emergency surgery may be required to avoid permanent weakness or paralysis.
Seek emergency medical attention if you have:
Worsening symptoms. Pain, numbness or weakness may increase to the point that you can't perform your usual daily activities.
Bladder or bowel dysfunction. People who have the cauda equina syndrome may become incontinent or have difficulty urinating even with a full bladder.
Saddle anesthesia. This progressive loss of sensation affects the areas that would touch a saddle — the inner thighs, back of legs and the area around the re**um.
WHAT YOU CAN DO
Before your appointment, write a list that answers the following questions:
When did you first begin experiencing symptoms?
Were you lifting, pushing or pulling anything at the time you first felt symptoms? Were you twisting your back?
Has the pain kept you from participating in activities you wanted to do?
What, if anything, seems to improve your symptoms?
What, if anything, appears to worsen your symptoms?
What medications or supplements do you take?
WHAT TO EXPECT FROM YOUR DOCTOR
Your doctor might ask some of the following questions:
Do you have any pain that travels into your arms or legs?
Do you feel any weakness or numbness in your arms or legs?
Have you noticed any changes in your bowel or bladder habits?
Does coughing or sneezing worsen your leg pain?
Is the pain interfering with sleep or work?
