If you’ve ever experienced pain that starts in your lower back or buttock and travels down your leg, you’ve probably heard the term “sciatica.”
Sciatica is one of the most common reasons people seek help for back and leg pain. It can be painful, frustrating, and sometimes quite alarming, particularly when symptoms include numbness, tingling, or weakness.
The good news is that most people improve with time and appropriate management, without needing surgery. Understanding what sciatica is, what causes it, and how to manage it can help you recover with more confidence.
What Is Sciatica?
Many people think sciatica is a diagnosis.
In reality, sciatica is a description of symptoms.
Sciatica refers to pain that travels along the pathway of the sciatic nerve, typically from the lower back or buttock and down into the leg. It may also be accompanied by numbness, tingling, burning sensations, or weakness.
The sciatic nerve is the largest nerve in the body. It originates from several nerve roots in the lower spine before travelling through the buttock and down the leg.
When one of these nerve roots becomes irritated, sensitised or compressed, sciatic symptoms can occur.
What Does Sciatica Feel Like?
Symptoms vary from person to person.
Common descriptions include:
- Sharp or shooting pain down the leg
- Burning pain
- Pins and needles
- Numbness
- Electric shock-like sensations
- A feeling of weakness or heaviness in the leg
- Pain that worsens with prolonged sitting
For many people, symptoms affect only one side of the body.

There isn’t one single cause.
Several conditions can irritate or compress the nerve roots that contribute to the sciatic nerve.
Disc Bulges and Disc Herniations
One of the most common causes, particularly in younger adults, is a disc herniation.
A spinal disc can bulge or herniate and irritate a nearby nerve root, leading to pain that travels into the leg.
Spinal Stenosis
As we age, the spaces around the nerves in the spine can become narrower.
This narrowing, known as spinal stenosis, may contribute to sciatic symptoms, particularly in older adults.
Arthritis and Degenerative Changes
Age-related changes within the spine can sometimes contribute to nerve irritation and leg pain.
Other Causes
Less commonly, symptoms may be related to:
- Spondylolisthesis
- Spinal injuries
- Inflammatory conditions
- Piriformis-related sciatic nerve irritation
- Other conditions affecting the lower back and pelvis
Does a Disc Bulge Always Cause Sciatica?
No.
This is one of the most important things to understand.
Many people have disc bulges on MRI scans without any pain whatsoever.
Likewise, not everyone with sciatic symptoms has a significant disc injury.
Imaging findings are only one piece of the puzzle and should always be interpreted alongside a thorough clinical assessment.
This is why scans are not always required in the early stages of sciatica.
Should You Rest or Keep Moving?
For many years, people with sciatica were advised to stay in bed.
We now know that prolonged inactivity is usually not helpful.
While a brief period of reduced activity may be appropriate during severe flare-ups, most people recover better when they continue moving within their tolerance. Staying active can help maintain mobility, strength and confidence while symptoms settle.
Walking, gentle movement, and appropriately prescribed exercises are often encouraged as part of recovery.

Book Appointment NowWhat Exercises Help Sciatica?
There is no single exercise that works for everyone.
The best exercise depends on the underlying cause, your symptoms, and how your body responds to movement.
A rehabilitation program may include:
- Walking
- Mobility exercises
- Nerve gliding exercises
- Core strengthening
- Hip strengthening
- Gradual return-to-activity programs
The goal is not simply to stretch the sciatic nerve. The goal is to improve your ability to move and function with less pain.
When Should You Seek Urgent Medical Attention?
Most cases of sciatica are not emergencies.
However, urgent medical assessment is recommended if you experience:
- Loss of bladder control
- Loss of bowel control
- Numbness around the groin or saddle area
- Significant or rapidly worsening leg weakness
These symptoms may indicate a serious condition requiring immediate medical attention.
Will I Need Surgery?
In most cases, no.
The majority of people improve with conservative management such as education, movement, exercise, and time. Surgery is typically reserved for severe cases, persistent symptoms, or significant neurological deficits.
