Sciatica or Back Pain? Understanding the Difference
By Chris Dunmall DC | Aceso Chiropractic, Buckingham
One of the questions I often hear in clinic is:
"Do you think it's sciatica?"
Usually, someone is describing pain somewhere around their lower back, buttock or leg.
And it's an understandable question.
Sciatica is a term most people have heard, but it isn't always clear what it actually means.
Not every pain travelling into the leg is sciatica.
And not every episode of lower back pain involves a problem with a nerve.
So how do we tell the difference?
What Is Sciatica?
Sciatica describes symptoms associated with irritation or compression of nerve roots in the lower back that contribute to the sciatic nerve.
The sciatic nerve travels from the lower spine, through the buttock and down the leg.
When the nerve roots become irritated, people may experience pain or altered sensation travelling into the leg.
Typical symptoms can include:
Pain travelling from the buttock down the back of the leg
Burning, shooting or electric-like pain
Pins and needles
Numbness
Muscle weakness in some cases
Sciatica often affects one leg, although symptoms can vary considerably.
Interestingly, someone with sciatica may have relatively little back pain.
Their main complaint might be the leg.
How Is Sciatica Different From Ordinary Back Pain?
Lower back pain is a broad description of discomfort felt around the lumbar spine.
It can arise from many different structures and processes.
Sciatica is more specific.
It involves symptoms associated with irritation or compression of nerves contributing to the sciatic nerve.
But there's another important distinction.
Pain can travel into the buttock or thigh without necessarily involving an irritated nerve.
We call this referred pain.
Structures around the lower back and pelvis can sometimes produce pain felt elsewhere.
That's why the location of the pain alone doesn't always tell us exactly what's happening.
A careful history and examination are much more useful than guessing.
What Causes Sciatica?
One common cause is a lumbar disc problem that irritates or compresses a nearby nerve root.
But discs aren't the only possible explanation.
Age-related changes around the spine, including narrowing of the spaces through which nerves travel, can sometimes contribute.
And the reason for someone's symptoms may not be immediately obvious.
It's also worth remembering that changes seen on spinal scans aren't always responsible for pain.
Many people have disc bulges or degenerative changes without experiencing symptoms.
What matters is whether the findings fit with someone's history, examination and clinical presentation.
Does Sciatica Get Better on Its Own?
Often, yes.
Many episodes improve gradually over several weeks or months.
But recovery isn't identical for everyone.
Some people notice symptoms settling relatively quickly.
Others experience persistent pain, altered sensation or recurring episodes.
The important thing is to monitor how symptoms are changing, particularly if weakness or numbness develops.
Should You Rest or Keep Moving With Sciatica?
In most uncomplicated cases, remaining gently active is encouraged.
That might mean short walks, changing position regularly and continuing comfortable everyday activities.
Prolonged bed rest is generally discouraged.
But this doesn't mean pushing through severe symptoms or forcing stretches that make leg pain worse.
Different people respond to different movements.
Some find sitting particularly uncomfortable. Others notice symptoms when standing or walking.
The aim is to find an appropriate level of activity and gradually build from there.
When Is Sciatica an Emergency?
Most sciatica isn't an emergency.
However, certain symptoms require immediate medical attention.
Seek emergency assessment if you develop:
New problems controlling your bladder or bowels, or difficulty passing urine
Loss of sensation around your genitals or bottom
Severe or worsening weakness or numbness affecting both legs
Sciatica affecting both sides, particularly with other neurological symptoms
These can indicate a serious problem involving the nerves in the lower spine.
New or progressively worsening weakness in one leg, including foot drop, also needs prompt medical assessment.
Can Chiropractic Care Help Someone With Sciatica?
At Aceso Chiropractic, our first priority is understanding the nature of someone's symptoms.
That may involve assessing spinal movement, reflexes, strength, sensation and other neurological findings.
Sometimes chiropractic care may form part of an appropriate management plan for low back pain with sciatica.
Current NICE guidance recommends that manual therapy, where used, forms part of care that includes exercise.
But not every person with sciatica is suitable for chiropractic treatment.
Some may benefit more from medical management, rehabilitation, further investigation or specialist assessment.
That's why understanding the problem comes before deciding on treatment.
A Final Thought
It's tempting to put a label on pain as quickly as possible.
Sciatica. A slipped disc. A trapped nerve.
Sometimes those labels are helpful.
But understanding what they mean for the individual is far more important.
If you're experiencing back or leg pain, a careful assessment can help clarify what's happening and what the next step should be.
Because a good explanation is often the beginning of better decisions.
