What Is Sciatica?

Sciatica is a term that describes pain, tingling, numbness, or weakness that travels along the path of the sciatic nerve, which runs from the lower back through the buttock and down the back of the leg, sometimes reaching as far as the foot. It is one of the most common reasons I see people seeking physiotherapy help, and it can range from a mild, intermittent ache to a sharp, debilitating pain that makes sitting or walking extremely difficult.

It is important to understand that sciatica is a symptom, not a diagnosis in itself. The pain is the result of something irritating or compressing the sciatic nerve somewhere along its path.

Common Causes of Sciatic Nerve Irritation

Several conditions can cause the sciatic nerve to become compressed or inflamed:

  • A herniated or bulging lumbar disc pressing on the nerve root at the level of L4, L5, or S1
  • Lumbar spinal stenosis, a narrowing of the spinal canal that is more common with age
  • Piriformis syndrome, where the piriformis muscle in the buttock irritates the nerve as it passes nearby
  • Spondylolisthesis, where one vertebra slips forward on another
  • Prolonged sitting on a hard surface, which can compress the nerve directly in some cases

In Dubai, where desk-based work and long daily commutes are the norm, lumbar disc irritation and piriformis syndrome are particularly frequent contributors to sciatic symptoms.

How to Recognise Sciatic Symptoms

Sciatica tends to have a fairly recognisable pattern, though it varies between individuals:

  • Pain that starts in the lower back or buttock and radiates down one leg, usually only one side
  • A burning, shooting, or electric quality to the pain
  • Numbness or tingling in the leg, calf, or foot
  • Weakness in the leg or foot that may make walking feel unstable
  • Symptoms that worsen when sitting for long periods or when bending forward
  • Some people find relief lying down, while others feel worse at rest
Sciatica almost always has a specific mechanical cause that can be identified through careful assessment. Finding that cause is the first step toward effective recovery.

The Role of Physiotherapy in Sciatica Recovery

A physiotherapist will begin with a thorough assessment to determine where the nerve is being irritated and why. This includes testing reflexes, sensation, muscle strength in the leg, and the mobility of the lumbar spine and hips. Understanding the direction of movement that relieves versus aggravates the symptoms is particularly important for guiding treatment.

Physiotherapy for sciatica typically includes a combination of targeted exercise to reduce nerve irritation and improve spinal mobility, manual therapy to address stiffness in the lumbar and sacroiliac joints, neural mobilisation techniques to restore normal movement of the sciatic nerve, and education about positions and activities to avoid during the acute phase.

The majority of people with sciatica recover well with conservative physiotherapy management, often avoiding the need for injections or surgery. Consistency with a home exercise programme is one of the most significant factors in a successful outcome.

When to Seek Help Promptly

While most cases of sciatica can be managed conservatively, certain symptoms require urgent medical attention. If you experience loss of bladder or bowel control alongside your leg symptoms, numbness in the inner thighs or around the groin, or rapidly worsening weakness in both legs, please seek medical attention immediately as these can indicate a serious condition called cauda equina syndrome.

For everything else, early physiotherapy assessment leads to significantly better outcomes than waiting. If you are dealing with sciatic pain and would like to understand what is driving it, book a consultation with Dr. Smruti Rathod.
