Sciatica Relief: A Centurion Physiotherapist's Guide
Sciatica is not really a diagnosis, it is a symptom: pain, tingling or weakness that travels down the leg because the sciatic nerve is irritated somewhere along its path. Understanding the real cause is what turns weeks of misery into a clear recovery plan.
What sciatica actually is
The sciatic nerve is the largest nerve in the body. It exits the lower spine, passes through the buttock and travels all the way down the leg. When something compresses or irritates the nerve, along its journey, you feel pain, pins and needles, numbness or weakness in the areas the nerve supplies.
The four most common causes
The four causes we see most often in Centurion are lumbar disc bulges pressing on a nerve root, degenerative narrowing of the spinal canal, piriformis syndrome where a deep buttock muscle irritates the nerve, and simple postural overload from long hours of sitting or driving. Treatment differs meaningfully between them, which is why an accurate assessment matters.
How physiotherapy treats sciatica
We start by identifying which structure is driving the irritation. Treatment then usually combines gentle joint mobilisation, targeted soft tissue work, nerve gliding exercises, and progressive strengthening of the deep core and glute muscles. Dry needling can be very useful for the deep buttock muscles when piriformis involvement is a factor.
Things that make sciatica worse
Prolonged sitting, deep couches, heavy lifting with a rounded back, high impact running early in the recovery, and complete bed rest all tend to make sciatica worse. Gentle, frequent movement is almost always better than lying still.
When to seek urgent care
See a doctor or emergency room immediately if you develop numbness in the saddle area, new loss of bladder or bowel control, or rapidly progressive weakness in a leg. These are rare but serious signs that need urgent investigation.

Keep moving within tolerance. Long periods of bed rest tend to slow recovery.
