Sciatica symptoms occur when the sciatic nerve or one of its nerve roots becomes irritated or compressed. The most characteristic symptom is pain that travels from the lower back or buttock into the leg, usually on one side.

Sciatica is not a condition with one single cause. It can result from problems affecting the lower spine, including a herniated disc, narrowing around the spinal nerves, or age-related changes in the spine.

Symptoms can range from mild discomfort to significant pain and may include numbness, tingling, or weakness in the affected leg. Many cases improve with conservative care, although persistent, severe, or worsening symptoms may require professional assessment.

What Is Sciatica?

The sciatic nerve is the largest nerve in the body. It is formed by nerve roots from the lower spine and travels through the buttocks and down each leg.

Sciatica describes symptoms caused by irritation or compression of the sciatic nerve or its contributing nerve roots.

The condition is different from ordinary lower back pain because symptoms commonly extend into the buttock, thigh, calf, or foot.

Sciatica usually affects one side of the body, although symptoms can occur on both sides in some situations.

What Are the Symptoms of Sciatica?

The most common sciatica symptom is radiating pain that travels from the lower back or buttock into the leg.

The pain can feel different from person to person. Some people describe it as:

• Sharp or shooting
• Burning
• Electric or shock-like
• Aching
• Tingling or pins and needles

Other possible sciatica symptoms include:

• Pain in the lower back or buttock
• Pain that travels down the back or side of the leg
• Numbness in the leg or foot
• Tingling in the leg, foot, or toes
• Weakness in the affected leg or foot
• Difficulty moving the leg or foot normally
• Symptoms that become worse with certain movements or positions

Not everyone with sciatica experiences all of these symptoms.

Where Is Sciatica Pain Located?

Sciatica pain commonly follows the path of the sciatic nerve.

It may be felt in:

Lower back → Buttock → Back or side of thigh → Calf → Foot or toes

The exact location depends on which nerve root is affected.

Some people experience mainly buttock and leg pain, while others may have symptoms that extend all the way to the foot.

What Causes Sciatica?

Several conditions can irritate or compress the nerve roots that contribute to the sciatic nerve.

Herniated Disc

A herniated disc occurs when material from an intervertebral disc pushes beyond its normal position and may irritate a nearby nerve root.

This is one of the common causes of sciatica, particularly in younger and middle-aged adults.

Spinal Stenosis

Spinal stenosis occurs when spaces around the spinal nerves become narrowed. This can place pressure on nerve structures and contribute to leg pain and other neurological symptoms.

Spondylolisthesis

Spondylolisthesis occurs when one vertebra shifts relative to another. In some cases, this can contribute to narrowing or nerve compression.

Age-Related Spinal Changes

Changes in the discs, joints, and other structures of the spine become more common with age. Some of these changes can contribute to narrowing around the nerves and sciatica symptoms.

Muscle or Soft-Tissue Factors

Muscle and soft-tissue problems around the lower back and hip can sometimes produce symptoms that resemble sciatica. This is one reason a proper assessment is important rather than assuming that every type of leg pain is caused by sciatic nerve compression.

What Can Make Sciatica Symptoms Worse?

Certain activities or positions may aggravate symptoms depending on the underlying cause.

Potential aggravating factors include:

• Prolonged sitting
• Certain lifting movements
• Repetitive bending or twisting
• Sudden increases in physical activity
• Some forms of exercise
• Positions that increase pressure or irritation around the affected nerve

The effect varies between individuals. An activity that aggravates one person’s symptoms may be comfortable for another.

Who Is More Likely to Develop Sciatica?

Several factors may increase the likelihood of experiencing sciatica, including:

• Increasing age and spinal changes
• Occupations involving prolonged sitting
• Frequent heavy lifting
• Repetitive bending or twisting
• Physically demanding work
• Certain sports or activities
• Higher body weight
• Previous lower back problems

Having a risk factor does not necessarily mean that a person will develop sciatica.

How Is Sciatica Diagnosed?

Sciatica is usually diagnosed through a combination of medical history and physical examination.

A healthcare professional may ask about:

• Where the pain begins and travels
• How long symptoms have been present
• Activities or positions that change symptoms
• Numbness or tingling
• Weakness
• Previous injuries or back problems
• Changes in bladder or bowel function

A physical examination may assess:

• Muscle strength
• Reflexes
• Sensation
• Walking pattern
• Spinal and leg movement
• Symptoms produced by specific movements
• Nerve tension

The aim is to determine whether symptoms are consistent with nerve involvement and whether further investigation is necessary.

Does Sciatica Always Require an MRI?

No.

Imaging is not automatically required for every person with sciatica. Many cases can initially be assessed based on symptoms and clinical examination.

An MRI or other imaging may be considered when symptoms are persistent, severe, unusual, or when the results could influence treatment decisions.

Possible investigations include:

X-Ray

X-rays primarily show bones and can help identify certain structural changes, but they do not provide the same detail about nerves and discs as MRI.

MRI

MRI provides detailed images of the spine, discs, nerves, and surrounding soft tissues. It may be used when there is a clinical reason to investigate possible nerve compression or another spinal problem.

CT Scan

CT can provide detailed images of spinal structures and may be used in particular clinical circumstances.

EMG and Nerve Conduction Testing

These tests assess electrical nerve and muscle function and may sometimes be used when the diagnosis or location of nerve involvement is unclear.

How Is Sciatica Treated?

Treatment depends on the underlying cause, severity of symptoms, duration, and functional limitations.

For many people, initial treatment is conservative.

Staying Active

Complete inactivity is generally not necessary for uncomplicated sciatica.

Maintaining appropriate movement and gradually returning to normal activities may form part of recovery. Activities should be adjusted if they significantly aggravate symptoms.

Exercise and Physiotherapy

Physiotherapy can help people manage sciatica through an individually tailored rehabilitation programme.

Depending on the assessment, treatment may include:

• Mobility exercises
• Strengthening
• Core and trunk conditioning
• Movement education
• Activity modification
• Manual therapy where appropriate
• Progressive return to physical activity

The specific exercises should be selected according to the individual’s symptoms and functional needs.

Medication

Depending on the individual’s circumstances, a doctor or other qualified healthcare professional may recommend medication for pain management.

Medication should be selected based on the person’s health history and potential risks rather than used as a universal treatment for sciatica.

Injections

In selected cases where symptoms are persistent or severe, a healthcare professional may consider an injection around an affected nerve root or other targeted treatment.

The suitability and potential benefits depend on the underlying diagnosis.

Surgery

Surgery is not required for most people with sciatica.

It may be considered when there is significant nerve compression, persistent symptoms despite appropriate non-surgical treatment, or certain neurological problems.

The decision depends on the underlying cause, severity of symptoms, neurological findings, and overall clinical assessment.

How Long Does Sciatica Last?

The duration of sciatica varies considerably.

Some episodes improve over several weeks with conservative management, while symptoms can persist longer in other cases.

Recovery depends on factors such as:

• The underlying cause
• Severity of nerve irritation
• Duration of symptoms
• Presence of neurological symptoms
• General health and activity level
• Response to treatment

Persistent or worsening symptoms should be assessed rather than relying solely on self-care.

Sciatica vs Lower Back Pain: What’s the Difference?

Lower back pain and sciatica are not the same thing.

Lower back pain may remain primarily around the lower back and can result from several different structures.

Sciatica typically involves symptoms extending from the lower back or buttock into the leg because of irritation or compression involving the sciatic nerve or its contributing nerve roots.

This distinction is useful because the appropriate assessment and treatment can differ.

When Should You Seek Help for Sciatica?

Consider professional assessment if:

• Leg pain persists or keeps returning
• Symptoms interfere with walking or daily activities
• Numbness or tingling continues
• You experience weakness in the leg or foot
• Pain is affecting sleep or work
• Symptoms are progressively worsening
• You are struggling to return to exercise or sport
• You are unsure whether your symptoms are actually sciatica

A physiotherapist can assess movement, neurological symptoms, functional limitations, and contributing factors and determine whether physiotherapy is appropriate.

Sciatica Red Flags: When to Seek Urgent Medical Care

Some symptoms require urgent medical assessment.

Seek prompt medical attention if you develop:

• New or worsening significant weakness in the leg
• Loss of bladder or bowel control
• Numbness around the inner thighs, genitals, or buttocks
• Severe symptoms affecting both legs
• Other sudden or significant neurological changes

These symptoms should not be managed with home remedies alone.
