Back Pain: Causes, Symptoms, Risk Factors, Diagnosis And Treatment

What Is Back Pain?

You can develop back pain from an injury, certain medical conditions and physical activity. Back pain an affect people of any age, but the chance of developing lower back pain increases with age [2].

Back pain can develop in the upper back and lower back. Lower back pain may be linked to the bony lumbar spine, discs between the vertebrae, spinal cord and nerves, lower back muscles and the skin around the lumbar area [3]. And upper back pain may be due to disorders of the aorta, tumours in the chest, and spine inflammation [4].

One of the leading cause of disability worldwide, back pain is something most people ignore. However, it is important that you pay attention because prolonged pain in the back can contribute towards the development of several health problems in the future.

Back pain is categorised into two types, acute pain and chronic or long-term pain. Acute pain starts suddenly and lasts for up to 6 weeks and chronic or long-term pain develops over a longer period, lasts for over 3 months, and causes problems [5].

What Are The Causes Of Back Pain?

Back pain often develops without a cause that your doctor can identify. The most common causes of back pain are strain and poor posture.

• Muscle strain or sprain: Strained muscles and ligaments, a muscle spasm, muscle tension, damaged disks, injuries, fractures, or falls can cause back pain [6]. Lifting something improperly, something that is too heavy and making an abrupt and awkward movement can strain your back, leading to pain.
• Bulging or ruptured discs: Each vertebra in the spine is cushioned by discs, that is the discs act as cushions between the bones [7]. Ageing, trauma to the spine, weight gain, smoking, and repetitive stress to the spine from sitting for long hours can cause the discs to deteriorate over time and cause them to protrude outside (bulging disc) [8].Without treatment, the bulging disc can eventually tear and cause sharp back pain that can move down into the buttocks, groin and down the legs.
• Osteoporosis: This condition can affect any joint in the body, including the small joints of the spine and causes the bones to become porous and brittle, therefore causing compression fractures that can lead to back pain [9].
• Arthritis: Osteoarthritis can cause problems with the joints in the hips and lower back [10]. This type of arthritis develops as a result of wear and tear of the cartilage, which causes a dull, aching, or throbbing pain which becomes worse with movement [11].

...

• Sciatica: It is the compression or pinching of the sciatic nerve, which is caused by injury or trauma to the pelvis, buttocks, or thigh, diabetes and prolonged sitting [12].
• Kidney problems: Kidney stones or kidney infection can cause back pain [13].
• An abnormal curve of the spine: If an individual has an abnormal curve in the spine, such as scoliosis, it can lead to severe back pain [14].

Some of the other causes of back pain are as follows [15]:

• Cauda equina syndrome (a bindle of spinal nerve roots)
• Cancer of the spine
• Ankylosing spondylitis (a chronic inflammatory disease of the spine joints)
• Infections such as pelvic inflammatory disease or bladder infections
• Spondylolysis
• Spinal stenosis
• Sleep disorders
• Shingles
• Twisting
• Coughing or sneezing
• Muscle tension
• Over-stretching
• Bending awkwardly or for long periods
• Pushing, pulling, lifting, or carrying something heavy
• Straining the neck forward
• Sleeping on a mattress that does not support the body

• Bone scans

What Is The Treatment For Back Pain?

Most acute back pain gets better with a few weeks of home treatment such as using over-the-counter pain relief medication and applying a hot compress or an ice pack to the painful area. One should rest plenty and move around to ease stiffness and to reduce pain [21].

Depending on the type of back pain you have you may be prescribed muscle relaxants, topical pain relievers, narcotics (opioids), antidepressants and injections. Some people will require surgery for back pain.

Transcutaneous electrical nerve stimulation (TENS) is a popular therapy for patients with chronic back pain.
