Topic Overview
Most people will have a minor back problem at one time or another.
Our body movements usually do not cause problems, but it's not surprising that
symptoms develop from everyday wear and tear, overuse, or injury. Back problems
and injuries often occur during sports or recreational activities, work-related
tasks, or home projects.
Back pain can cause problems anywhere from the neck to the
tailbone (coccyx). The back includes:
- The bones and joints of the spine (vertebrae
). - The
discs
that separate the vertebrae and absorb shock as
you move. - The muscles and
ligaments that hold the spine together.
Back injuries are the most common cause of back pain.
Injuries frequently occur when you use your back muscles in activities that you
do not do very often, such as lifting a heavy object or doing yard work. Minor
injuries also may occur from tripping, falling a short distance, or excessive
twisting of the spine. Severe back injuries may result from car accidents,
falls from significant heights, direct blows to the back or the top of the
head, a high-energy fall onto the buttocks, or a penetrating injury such as a
stab wound.
Although back pain is often caused by an injury to one or more of
the structures of the back, it may have another cause. Some people are more
likely to develop back pain than others.
Factors that increase your risk for back pain and
injury include getting older, having a family history of back pain, sitting for
long periods, lifting or pulling heavy objects, or having a degenerative
disease such as
osteoporosis.
Low back pain may occur in
children and teenagers, but children and teens are
less likely to see a doctor for low back pain. Although most back problems
occur in adults who are between the ages of 20 and 50, back problems in
children who are younger than 20 and adults who are older than 50 are more
likely to have a serious cause.
Sudden (acute) injuries
Pain from an injury may be sudden and severe. Bruising and
swelling may develop soon after the injury. Pain from an acute injury usually
does not last longer than 6 weeks. Acute injuries include:
- An injury to the ligaments or muscles in the
back, such as a
sprain or a
strain.
- A fracture or dislocation of the
spine. This can cause a spinal cord injury that may lead to permanent
paralysis. It is important to immobilize and transport the injured person
correctly to reduce the risk of permanent paralysis. See
first aid for a spinal injury.
- A torn or
ruptured disc. If the tear is large enough, the jelly-like material inside the
disc may leak out (herniate) and press against a nerve. See a picture of a
herniated
disc
or

. - Compression of nerves in the lower back
(cauda equina syndrome).
Overuse injuries
- You may not remember a specific injury,
especially if your symptoms began gradually or during everyday activities.
These injuries occur most often from improper movement or posture while
lifting
, standing, walking, or sitting, or even while
sleeping
. Symptoms can include pain, muscle spasms,
and stiffness. The pain often goes away within 4 weeks without any
treatment.
Conditions that may cause back problems
Back problems may not be related to an injury.
- Conditions that weaken the spine, such as
osteoarthritis,
osteoporosis,
spinal stenosis, or
Paget's disease, can cause back pain. These conditions
are most common in older adults. In rare cases, tumours or infections can
develop in or around the spine.
- Some
medical conditions can cause pain to spread to the
back from other parts of the body (referred pain). Many health problems that
can cause back pain have nothing to do with the bones, joints, muscles, or
ligaments of the back.
- Spinal deformities such as
scoliosis,
kyphosis (Scheuermann's disease), and
spondylolisthesis can cause back
pain.
- Chronic pain syndrome caused by a previous injury or
degenerative disease with aging can cause back pain.
Treatment
Most back pain will get better and go away by itself in 1 to 4
weeks. Home treatment will often help relieve back pain that is caused by minor
injuries. It is usually a good idea to continue your regular activities while
your back is healing. Avoid heavy lifting and activities that seem to make your
back problems worse.
Other treatments for a back problem or injury may include first
aid measures, physiotherapy, manipulative therapy (such as chiropractic),
medicine, and in some cases, surgery. Treatment depends on:
- The location, type, and severity of the
injury.
- Your age, health condition, and activities (such as work,
sports, or hobbies).
