Sciatica

What Is Sciatica?

Sciatica describes symptoms caused by irritation of the sciatic nerve or the nerve roots in the lower back.

The sciatic nerve is the largest nerve in the body. It begins in the lower back, passes through the buttocks and travels down the back of each leg into the feet.

When the nerve becomes irritated, symptoms can be felt anywhere along its pathway.

Sciatica is not a diagnosis in itself. Rather, it is a term used to describe a particular pattern of symptoms.

Common Symptoms

Sciatica can feel different from person to person.

Pain Travelling Down The Leg

Pain may travel from the lower back or buttock into the thigh, calf or foot.

Burning Or Electric Shock-Like Pain

Some people describe the pain as burning, shooting, sharp or electric in nature.

Tingling Or Pins And Needles

Altered sensations may occur anywhere in the leg or foot.

Numbness

Some people notice patches of reduced sensation.

Weakness

Occasionally, muscles supplied by the affected nerve may feel weaker.

Lower Back Pain

Many people experience both lower back pain and leg symptoms, although the leg pain is often more noticeable.

What Causes Sciatica?

Sciatica can occur for several reasons.

Disc-Related Changes

Changes in a spinal disc can sometimes contribute to irritation of nearby nerve roots.

Discs are normal structures that sit between the bones of the spine and help absorb forces during movement.

Inflammation Around The Nerve

Sometimes inflammation can sensitise a nerve without significant compression.

Age-Related Changes

Normal age-related changes within the spine may occasionally contribute to symptoms.

Spinal Narrowing

In some cases, narrowing around the nerves can contribute to irritation.

No Single Identifiable Cause

Sometimes it is difficult to identify one specific structure responsible for symptoms.

This is common and does not necessarily affect recovery.

Is Sciatica Always Caused By A Trapped Nerve?

Not necessarily.

The term “trapped nerve” is commonly used but can be misleading.

Nerves are living, sensitive tissues that can become irritated for a variety of reasons. Symptoms may occur because of compression, inflammation, chemical irritation or increased sensitivity within the nervous system.

For many people, it is more accurate to think of the nerve as irritated rather than trapped.

Does Pain Mean Damage?

Not necessarily.

Sciatica can be extremely painful, but the intensity of symptoms does not always reflect the amount of tissue damage present.

Many people recover fully without surgery or invasive treatment.

Pain is a protective warning system and can sometimes become highly sensitive, particularly when symptoms have been present for longer periods.

Do I Need An MRI Scan?

Most people with sciatica do not need an MRI scan in the early stages.

Many MRI findings are common in people who have no symptoms at all, including:

• Disc bulges
• Disc degeneration
• Arthritic changes

For this reason, scans do not always provide clear answers.

An MRI may be considered if symptoms are severe, worsening, not improving as expected, or if there are concerns about a more serious condition.

How Long Does Sciatica Last?

Recovery varies from person to person.

Many people notice significant improvement within a few weeks, while others may take several months to fully recover.

Nerves can take time to settle, and recovery is often gradual rather than perfectly linear.

It is common to experience good days and bad days during recovery. Temporary flare-ups do not necessarily mean that damage is worsening.

Should I Keep Walking?

In many cases, yes.

Walking is often one of the most helpful activities for people with sciatica.

You do not need to ignore severe symptoms, but remaining as active as reasonably possible is generally encouraged.

Activity can help maintain confidence, reduce stiffness and support recovery.

Should I Rest?

Short periods of relative rest may be helpful during severe flare-ups.

However, prolonged bed rest is usually not recommended.

Most people recover better when they gradually return to normal activities.

Factors That Can Influence Recovery

Recovery is influenced by more than what is happening in the lower back alone.

Several factors may affect symptoms and recovery, including:

• Sleep quality
• Stress levels
• Physical activity levels
• General health and fitness
• Smoking
• Confidence in movement
• Fear of causing damage

This does not mean symptoms are “all in your head.” These factors have genuine physical effects on how pain is experienced and how the body recovers.

Common Myths About Sciatica

Myth: Sciatica Means My Nerve Is Permanently Damaged

Most people recover well and nerves are often capable of healing and becoming less sensitive over time.

Myth: Severe Pain Means Severe Damage

Pain intensity does not always reflect the amount of tissue damage present.

Myth: I Need A Scan Immediately

Most people improve without needing imaging or surgery.

Myth: I Should Stay In Bed Until It Settles

Extended rest is rarely helpful and may delay recovery.

Myth: Surgery Is Usually Necessary

The majority of people improve with time, movement and conservative management.

What Can You Do Yourself?

Keep Moving

Gentle movement is often beneficial.

Walk Regularly

Walking can help many people remain active and maintain confidence.

Pace Activities

Try to avoid large swings between overdoing activity and complete rest.

Prioritise Sleep

Good sleep can positively influence recovery.

Stay Reassured

Most episodes improve with time. Understanding the condition can often reduce fear and uncertainty.

Common Sciatica Problems

Pain travelling into the buttock

Pain extending below the knee

Pins and needles in the leg or foot

Numbness in the leg

Sciatica after lifting

Sciatica after prolonged sitting

Recurring episodes of sciatica

Sciatica associated with lower back pain

When Should You Seek Medical Advice?

Consider seeking professional advice if:

• Symptoms are not improving
• Pain is affecting sleep or daily activities
• Symptoms keep returning
• You are developing weakness in the leg
• You are unsure what may be causing your symptoms

Urgent medical attention should be sought if you experience:

• Loss of bladder or bowel control
• Numbness around the genitals, buttocks or inner thighs
• Significant weakness in both legs
• Rapidly worsening neurological symptoms

These symptoms are uncommon but require immediate assessment.

Can Osteopathy Help?

Osteopathy may help some people manage sciatica through assessment, education, hands-on treatment and exercise advice.

Assessment

A thorough assessment can help identify contributing factors and determine whether further investigation may be needed.

Hands-On Treatment

Treatment may include mobilisation, stretching, massage and other manual techniques aimed at improving movement and reducing discomfort.

Exercise Advice

Exercises may help improve mobility, confidence and function.

Education And Reassurance

Understanding your symptoms can be an important part of recovery.

Many people find that having a clear explanation and practical plan helps reduce worry and improve confidence.
