Backache or Sciatica? Understanding the Difference

Article Highlight

This article highlights Dr Colum Nolan’s contribution to a feature originally published by Mount Elizabeth Hospitals Health Plus, where he shares insights on back pain, sciatica, and when symptoms may require medical assessment.

Back pain is one of the most common musculoskeletal complaints, affecting people of all ages and lifestyles. While many episodes are related to muscle strain or everyday activities, pain that travels from the lower back down the leg may indicate a different condition known as sciatica.

In a recent Mount Elizabeth Hospitals Health Plus feature, Dr Colum Nolan explains why recognising the difference between general back pain and sciatica is important, as identifying the underlying cause helps guide the most appropriate treatment.

Back Pain and Sciatica Are Different Conditions

Although both conditions can cause discomfort in the lower back, they do not always share the same cause. Back pain commonly arises from muscles, ligaments, joints, or age-related changes within the spine. In many cases, symptoms improve with conservative treatment and activity modification.
Sciatica, however, occurs when the sciatic nerve becomes irritated or compressed, often due to conditions such as a slipped (herniated) disc or spinal stenosis. Rather than remaining localised to the back, symptoms frequently radiate into the buttock, thigh, or leg.

Symptoms That May Suggest Sciatica

While back pain is common, certain symptoms may indicate that a nerve is involved.
These include:
  • Pain travelling from the lower back into the buttock or leg
  • Tingling or numbness in the leg or foot
  • Burning or electric shock-like pain
  • Weakness in the affected leg
  • Symptoms that worsen with prolonged sitting, coughing, or sneezing
Recognising these symptoms early may help patients seek appropriate assessment before symptoms progress further.

Most Patients Do Not Need Surgery

One of the common misconceptions surrounding spine conditions is that surgery is always required. In reality, many patients improve with conservative treatments such as medication, physiotherapy, activity modification, or targeted injections. Surgery is generally considered only when symptoms persist despite appropriate treatment, progressively worsen, or when there is significant nerve compression affecting strength or function. The most appropriate treatment depends on the individual’s symptoms, examination findings, and imaging results.

When Should You Seek Medical Assessment?

While occasional back pain often improves with time, medical assessment should be considered if symptoms include:
  • Pain travelling down one or both legs
  • Persistent tingling or numbness
  • Weakness affecting the leg or foot
  • Difficulty walking
  • Symptoms that continue despite rest or conservative treatment
  • Changes in bladder or bowel function, which require urgent medical attention
Early assessment helps determine whether symptoms are related to muscles, joints, discs, or nerves, allowing treatment to be tailored appropriately.
