Sciatica vs Back Pain – How Can You Tell the Difference?
Many people use the terms back pain and sciatica interchangeably, but they are not actually the same condition.
While sciatica often causes back pain, not all back pain is sciatica.
Understanding the difference can help you decide when to seek professional advice and ensure you receive the most appropriate treatment.
At One2One Therapy Bridgend, we regularly assess people experiencing lower back pain, leg pain and symptoms that may be related to irritation of the sciatic nerve.
What Is Back Pain?
Back pain is a general term used to describe pain felt anywhere in the back, although it most commonly affects the lower back (lumbar spine).
It can develop suddenly after lifting, twisting or exercising, or it may gradually build up over weeks or months.
Common causes include:
- Muscle strain
- Joint irritation
- Poor posture
- Heavy lifting
- Reduced movement
- Arthritis
- Sports injuries
Most episodes improve with appropriate movement, exercise and advice.
What Is Sciatica?
Sciatica is not a condition itself.
It describes symptoms caused by irritation or compression of the sciatic nerve, which is the largest nerve in the body.
The sciatic nerve begins in the lower back before travelling through the buttock and down each leg.
When irritated, symptoms may travel anywhere along that nerve pathway.
Common Symptoms of Sciatica
People with sciatica may experience:
- Pain travelling from the lower back into the buttock
- Pain down the back of the leg
- Burning pain
- Sharp shooting pain
- Pins and needles
- Numbness
- Muscle weakness
Some people experience very little back pain but significant leg pain.
Signs It May Be Back Pain Instead
Simple lower back pain often:
- Stays around the lower back
- May spread slightly into the buttocks
- Does not usually travel below the knee
- Feels stiff after sitting
- Improves as you begin moving
Although uncomfortable, ordinary back pain usually behaves differently to true sciatica.
Sciatica vs Back Pain
| Back Pain | Sciatica |
|---|---|
| Usually stays in lower back | Often travels into the leg |
| Aching or stiffness | Burning or shooting pain |
| Rarely causes numbness | Pins and needles common |
| Usually no leg weakness | Weakness can occur |
| Often movement-related | Nerve symptoms more noticeable |
What Causes Sciatica?
Several conditions can irritate the sciatic nerve, including:
- Disc injuries
- Degenerative changes
- Spinal narrowing (stenosis)
- Inflammation
- Muscle irritation around the nerve
A physiotherapy assessment helps determine what may be contributing to your symptoms.
Should You Keep Walking?
Many people ask whether walking is good for sciatica.
For some people, gentle walking helps reduce stiffness and maintain movement.
Others may find prolonged walking temporarily increases symptoms.
The best advice depends on your individual presentation, which is why personalised assessment is important.
When Should You Seek Physiotherapy?
Book an assessment if:
- Pain lasts longer than two weeks
- Symptoms travel below your knee
- You have recurring episodes
- Walking becomes difficult
- You're struggling to work
- Sleep is affected
- Painkillers aren't helping
Early assessment often prevents symptoms becoming more persistent.
When Should You Seek Urgent Medical Attention?
Although uncommon, seek urgent medical advice if you experience:
- Loss of bladder or bowel control
- Numbness around the saddle area
- Significant leg weakness
- Difficulty walking
- Rapidly worsening symptoms
These require immediate medical assessment.
