Lower Back Pain: Do I need Imaging or Scans?

Lower Back Pain (LBP) is a very common musculoskeletal problem which 80 % of the population may experience this at some point in their lives. This condition can be found in the workforce, from office workers to those whose work is more physically demanding. It is also prevalent in various age groups, from adolescents to the elderly. LBP can cause significant pain and may affect daily activity or work, even prevent you from participating in your leisure activity. Although it can be alarming, the prognosis for the majority of LBP cases is good.

What is Lower Back Pain?

The definition of lower back pain is pain, ache, or discomfort in the lower back region. This may come with or without buttock or leg pain, pins and needles sensation, numbness, weakness or other symptoms such as spasms,

What causes pain in Lower Back Pain?

The Lower Back is a complex region with many structures that may contribute to the pain you are feeling. Due to this complexity, it is often difficult to determine one specific cause of the pain. Because of this, the LBP in this category is often called as “Non-specific Lower Back Pain”. The majority of LBP cases are not associated with serious conditions, such as fracture, significant nerve compression, or other sinister pathologies. Your health practitioner will check if you have any signs or symptoms of these conditions and take further action accordingly if needed.

Is imaging/scan for Lower Back Pain necessary (x-ray, MRI, CT-scan)?

Imaging is not recommended for most cases of Lower Back Pain, unless there is a suspicion of serious conditions as described above. Research found that lower back scans on the general population often show “Wear and tear” changes even in those without Lower Back Pain. This shows that “wear and tear” does not always equate to pain, i.e. the degeneration or disc bulge finding in your imaging may not necessarily be the cause of your Lower Back Pain. In fact, the result of imaging may cause you to wrongly associate the normal “wear and tear” as the cause of pain and a misunderstanding that your pain will persist. Additionally, the imaging result often does not change the management of your Lower Back Pain.

What can I do to manage my Lower Back Pain?
