What is a herniated disc?
(vertebrae) that form the
spine in your back are cushioned by small, spongy
discs. When these discs are healthy, they act as shock absorbers for the spine
and keep the spine flexible. But when a disc is damaged, it may bulge or break
open. This is called a herniated disc . It may also be called a slipped or
You can have a herniated
disc in any part of your spine. But most herniated discs affect the lower back
(lumbar spine). Some happen in the neck (cervical spine) and, more rarely, in
the upper back (thoracic spine).
What causes a herniated disc?
A herniated disc may be caused by:
- Wear and tear of the disc. As you age, your
discs dry out and aren't as flexible.
- Injury to the spine. This may
cause tiny tears or cracks in the hard outer layer of the disc. When this
happens, the thick gel inside the disc can be forced out through the tears or cracks
in the outer layer of the disc. This causes the disc to bulge or break open.
What are the symptoms?
herniated disc presses on
nerve roots , it can cause pain, numbness, and weakness
in the area of the body where the nerve travels. A herniated disc in the lower
back can cause pain and numbness in the buttock and down the leg. This is
called sciatica (say "sy-AT-ih-kuh"). Sciatica is the most
common symptom of a herniated disc in the low back.

you. If your symptoms clearly point to a herniated disc, you may not need

How is it treated?
Symptoms from a herniated disc
usually get better in a few weeks or months. To help you recover:
- Rest if you have severe pain. Otherwise, stay
active. Staying in bed for more than 1 or 2 days can weaken your muscles and
make the problem worse. Walking and other light activity may help.
- Try using a heating pad on a low or medium setting for 15 to 20 minutes every 2 or 3 hours. Try a warm
shower in place of one session with the heating pad. You can also buy single-use heat wraps that last up to 8 hours. You can also try an ice pack
for 10 to 15 minutes every 2 to 3 hours.
- Do the exercises that your
doctor or physical therapist suggests. These will help keep your back muscles
strong and prevent another injury.
- Ask your doctor about medicine
to treat your symptoms. Medicine won't cure a herniated disc, but it may help
with pain and swelling.
Usually a herniated disc will heal on its own over time.
About half of people with a herniated disc get better within 1 month, and most
are better within 6 months. Only about 1 person out of 10 eventually has

treatment plan. If your symptoms don't get better in a few months, you may want to
talk to your doctor about surgery.
Can a herniated disc be prevented?
After you have
hurt your back, you are more likely to have back problems in the future. To
help keep your back healthy:
- Protect your back when you lift. For example,
lift with your legs, not your back. Don't bend forward at the waist when you
lift. Bend your knees, and squat.
- Use good posture. When you stand
or walk, keep your shoulders back and down, your chin back, and your belly in.
This will help support your lower back.
- Get regular exercise.
- Stay at a healthy weight. This may reduce the load on your lower
- Don't smoke. Smoking increases the risk of a disc
