Back pain
Back pain is a common reason for absence from work and for seeking medical treatment. It can be uncomfortable and debilitating.
It can result from injury, activity, and some medical
conditions. Back pain can affect people of any age, for different reasons. As
people get older, the chance of developing lower back pain increases,
due to factors such as previous occupation and degenerative disk disease.
Lower
back pain may be linked to the bony lumbar spine, discs between the vertebrae,
ligaments around the spine and discs, spinal cord and nerves, lower back
muscles, abdominal and pelvic internal organs, and the skin around the lumbar
area.
Pain
in the upper back may be due to disorders of the aorta, tumors in the chest,
and spine inflammation.
The human back is composed of a complex structure of
muscles, ligaments, tendons, disks, and bones, which work together to support
the body and enable us to move around.
The
segments of the spine are cushioned with cartilage-like pads called disks.
Problems
with any of these components can lead to back pain. In some cases of back pain,
its cause remains unclear.
Damage
can result from strain, medical conditions, and poor posture, among others.
Strain
Back
pain commonly stems from strain, tension, or injury. Frequent causes of back pain are:
- strained muscles or ligaments
- a muscle spasm
- muscle tension
- damaged disks
- injuries, fractures, or falls
Activities
that can lead to strains or spasms include:
- lifting something improperly
- lifting something that is too heavy
- making an abrupt and awkward movement
Structural problems
A
number of structural problems may also result in back pain.
- Ruptured disks: Each
vertebra in the spine is cushioned by disks. If the disk ruptures there
will be more pressure on a nerve, resulting in back pain.
- Bulging disks: In
much the same way as ruptured disks, a bulging disk can result in more
pressure on a nerve.
- Sciatica: A
sharp and shooting pain travels through the buttock and down the back of
the leg, caused by a bulging or herniated disk pressing on a
nerve.
- Arthritis: Osteoarthritis
can cause problems with the joints in the hips, lower back, and other
places. In some cases, the space around the spinal cord narrows. This is
known as spinal stenosis.
- Abnormal curvature of the spine: If the spine curves in an unusual way, back pain
can result. An example is a scoliosis, in which the spine curves to the
side.
- Osteoporosis: Bones,
including the vertebrae of the spine, become brittle and porous, making
compression fractures more likely.
- Kidney problems:
Kidney stones or kidney infections can cause back pain.
Movement and posture
Adopting a very hunched sitting position when using computers can result in
increased back and shoulder problems over time.
Back
pain can also result from some everyday activities or poor posture.
Examples
include:
- twisting
- coughing or sneezing
- muscle tension
- over-stretching
- bending awkwardly or for long periods
- pushing, pulling, lifting, or carrying something
- standing or sitting for long periods
- straining the neck forward, such as when driving or
using a computer
- long driving sessions without a break, even when not
hunched
- sleeping on a mattress that does not support the body
and keep the spine straight
Other causes
Some
medical conditions can lead to back pain.
- Cauda equina syndrome: The cauda equine is a bundle of spinal nerve
roots that arise from the lower end of the spinal cord. Symptoms include dull pain in the lower back and upper buttocks, as well as numbness in the
buttocks, genitalia, and thighs. There are sometimes bowel and bladder
function disturbances.
- Cancer of the spine: A tumor on the spine may press against a
nerve, resulting in back pain.
- Infection of the spine: A fever and a tender, warm area on the
back could be due to an infection of the spine.
- Other infections: Pelvic inflammatory disease, bladder, or kidney
infections may also lead to back pain.
- Sleep disorders: Individuals
with sleep disorders are more likely to experience back pain, compared
with others.
- Shingles: An
infection that can affect the nerves may lead to back pain. This depends
on which nerves are affected.
You have to consult with your doctor for the medication for back pain.
