Back Pain - What should you know?



Back pain is a very common complaint. According to the Mayo Clinic, approximately 80% of all Americans will have low back pain at least once in their lives. Back pain is a common reason for absence from work, or visiting the doctor's.


According to the NHS (National Health Service), UK, back pain is the largest cause of work-related absence in the United Kingdom. Although back pain may be painful and uncomfortable, it is not usually serious. 



Even though back pain can affect people of any age, it is significantly more common among adults aged between 35 and 55 years. 



Experts say that back pain is associated with the way our bones, muscles and ligaments in our backs work together. 



Pain in the lower back 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, abdomen 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.

What are the causes of back pain?

The human back is composed of a complex structure of muscles, ligaments, tendons, disks and bones - the segments of our spine are cushioned with cartilage-like pads. Problems with any of these components can lead to back pain. In some cases of back pain, its cause is never found. 

Strain - the most common causes of back pain are:
  • Strained muscles
  • Strained ligaments
  • Lifting something improperly
  • Lifting something that is too heavy
  • The result of an abrupt and awkward movement
  • A muscle spasm.
Structural problems - the following structural problems may also result in back pain:
  • Ruptured disks - each vertebra in our 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 that travels through the buttock and down the back of the leg, caused by a bulging or herniated disk pressing on a nerve.
  • Arthritis - patients with osteoarthritis commonly experience problems with the joints in the hips, lower back, knees and hands. In some cases spinal stenosis can develop - the space around the spinal cord narrows.
  • Abnormal curvature of the spine - if the spine curves in an unusual way the patient is more likely to experience back pain. An example is scoliosis, when the spine curves to the side.
  • Osteoporosis - bones, including the vertebrae of the spine, become brittle and porous, making compression fractures more likely.

Below are some other causes of 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. People with cauda equine syndrome feel a dull pain in the lower back and upper buttocks, as well as analgesia (lack of feeling) in the buttocks, genitalia and thigh. There are sometimes bowel and bladder function disturbances.
  • Cancer of the spine - a tumor located on the spine may press against a nerve, resulting in back pain.
  • Infection of the spine - if the patient has an elevated body temperature (fever) as well as a tender warm area on the back, it could be caused by an infection of the spine.
  • Other infections - pelvic inflammatory disease (females), bladder or kidney infections.
  • Sleep disorders - individuals with sleep disorders are more likely to experience back pain, compared to others.
  • Shingles - an infection that can affect the nerves.
  • Bad mattress - if a mattress does not support specific parts of the body and keep the spine straight, there is a greater risk of developing back pain.
Everyday activities or poor posture
Back pain can also be the result of some everyday activity or poor posture. Examples include:
  • Bending awkwardly
  • Pushing something
  • Pulling something
  • Carrying something
  • Lifting something
  • Standing for long periods
  • Bending down for long periods
  • Twisting
  • Coughing
  • Sneezing
  • Muscle tension
  • Over-stretching
  • Sitting in a hunched position for long periods (e.g. when driving)
  • Long driving sessions without a break (even when not hunched).
