Sciatica can cause pain that starts in the lower back or buttock and travels down the leg, sometimes reaching the foot or toes. The pain may feel like a sharp electric shock, burning sensation or persistent ache. Some people also experience tingling, numbness or weakness in the affected leg.
If you are wondering, “Why does pain travel from my lower back to my leg?”, “How do I know if I have sciatica?” or “When should I see a specialist for sciatica?”, understanding the symptoms and possible causes can help you decide what to do next.
Sciatica is a symptom caused by irritation or compression of the sciatic nerve or the nerve roots that contribute to it. A herniated disc and narrowing of the spinal canal are among the possible causes. Many cases improve with time and appropriate non-surgical care, but persistent pain, worsening weakness or other warning signs require medical assessment.
If lower back pain spreads into your buttock or leg, identifying the underlying cause is important. The team at Manubhai Shah Medical & Research Centre – MS Medical Mumbai can guide you on the appropriate next steps for seeking medical evaluation.
What Is Sciatica?
The sciatic nerve is the largest nerve in the body. It originates from nerve roots in the lower spine and travels through the buttock and down each leg.
Sciatica describes symptoms that occur when the nerve roots or sciatic nerve are irritated or compressed. It is not a disease on its own; it usually indicates an underlying problem that needs to be assessed in the context of the person’s symptoms.
Sciatica most commonly affects one side of the body. Pain may begin in the lower back or buttock and extend down the back of the thigh, calf, foot or toes.
The severity varies. Some people experience mild discomfort, while others have pain that makes sitting, standing, walking or sleeping difficult.
What Are the Symptoms of Sciatica?
- Pain travelling down the leg: Pain may start in the lower back or buttock and extend towards the thigh, calf or foot.
- Sharp or shooting pain: The discomfort may feel like an electric shock or a sudden, stabbing sensation.
- Burning pain: Some people describe a burning feeling along the back of the leg.
- Tingling or pins and needles: The affected leg or foot may feel as though it is prickling.
- Numbness: Parts of the leg or foot may have reduced sensation.
- Muscle weakness: The affected leg or foot may feel weaker than usual.
- Pain that worsens with certain movements: Sitting for long periods, bending, coughing or sneezing may aggravate symptoms in some people.
Not everyone experiences all these symptoms. Some people have significant leg pain with little back pain, while others experience pain alongside numbness or weakness.
New or worsening muscle weakness should be assessed promptly rather than treated as ordinary back pain.
Why Does Pain Travel from the Lower Back to the Leg?
Pain that travels from the lower back to the leg can occur when a nerve root in the lower spine becomes irritated or compressed.
The sciatic nerve is formed from several nerve roots. When one of these roots is affected, pain or altered sensation may follow the nerve pathway into the buttock and leg.
For example, a herniated disc in the lower back may press against a nearby nerve root. This can cause pain that travels down the leg, sometimes with tingling, numbness or weakness.
However, not every case of lower back pain that spreads into the leg is sciatica. Hip conditions, muscle problems and other nerve disorders can produce similar symptoms. A clinical assessment can help distinguish between them.
What Causes Sciatica?
Several conditions can irritate or compress the nerve roots associated with the sciatic nerve.
Herniated or Slipped Disc
A spinal disc acts as a cushion between the bones of the spine. If part of the disc protrudes and presses on a nearby nerve root, it may cause sciatica.
Symptoms can include lower back discomfort, shooting leg pain, tingling or numbness. The severity depends on the location and extent of nerve irritation.
Spinal Stenosis
Spinal stenosis is a narrowing of the spaces within the spine. This narrowing can put pressure on the nerves and may cause pain, numbness or weakness in the legs.
Some people notice symptoms when standing or walking for longer periods, with relief when sitting or bending forward.
Age-Related Changes in the Spine
Changes in the spinal discs and joints can sometimes contribute to nerve compression. Bone spurs and other degenerative changes may narrow the spaces through which the nerves travel.
These findings do not always cause symptoms, so imaging results need to be interpreted alongside the clinical examination.
Spondylolisthesis
Spondylolisthesis occurs when one vertebra slips relative to another. In some cases, this can narrow the spaces around the nerves and contribute to sciatica-like symptoms.
Injury or Trauma
Certain back or pelvic injuries can affect the structures surrounding the sciatic nerve or its nerve roots. Pain following a serious accident or fall needs prompt medical assessment.
Other Causes
Less commonly, tumours, infections or other medical conditions may affect the spine or surrounding nerves. These possibilities are considered when symptoms, examination findings or medical history suggest a more serious underlying problem.
Who Is More Likely to Develop Sciatica?
Sciatica can affect adults of different ages, but some factors may increase the likelihood of developing it.
These include:
- Age-related changes in the spine
- Previous back problems or injuries
- Excess body weight
- Jobs involving frequent heavy lifting or twisting
- Prolonged sitting and limited physical activity
- Certain medical conditions, including diabetes, which can increase the risk of nerve problems
Having one or more risk factors does not mean that you will develop sciatica. People can also experience sciatica without an obvious trigger.
How Is Sciatica Diagnosed?
Sciatica is usually assessed through a medical history and physical examination. Imaging or other investigations may be recommended when the symptoms or clinical findings indicate a need.
Medical History
The clinician may ask:
- Where does the pain begin, and where does it travel?
- When did the symptoms start?
- Does sitting, standing, walking, coughing or bending change the pain?
- Have you noticed tingling, numbness or weakness?
- Have you experienced an injury or had similar symptoms before?
These details help the clinician understand the pattern of symptoms and consider possible causes.
Physical and Neurological Examination
The examination may include checking muscle strength, sensation, reflexes, walking ability and spinal movement.
The clinician may also perform specific movement tests to see whether they reproduce the symptoms. These tests can provide useful information, but no single examination finding establishes every diagnosis.
MRI Scan
An MRI may be recommended when symptoms are severe or persistent, when neurological findings raise concern, or when the results would help guide treatment.
MRI can show spinal discs, nerve roots and other soft tissues. However, disc changes can also occur in people without symptoms, so scan findings must be interpreted alongside the clinical assessment.
X-ray or CT Scan
An X-ray may help assess certain bone-related changes, fractures or spinal alignment. A CT scan may be useful in selected situations when more detailed bone imaging is needed or MRI is unsuitable. If you have been advised to have one, see how long a CT scan takes.
Neither test is routinely necessary for every person with sciatica.
Other Investigations
Blood tests or other investigations may be considered when a clinician suspects infection, inflammation or another underlying condition. In selected cases, nerve function tests such as a nerve conduction study may also be considered. The appropriate tests depend on the symptoms and medical history.

What Is the Best Treatment for Sciatica?
There is no single treatment that is best for everyone with sciatica. Treatment depends on the underlying cause, symptom severity, neurological findings and how much the pain affects daily life. Many people improve with conservative, non-surgical care.
Staying Active
Short periods of rest may help during severe discomfort, but prolonged bed rest is generally discouraged. Gentle movement and a gradual return to normal activities can support recovery.
Choose activities according to your symptoms and avoid movements that significantly worsen your pain. If walking is difficult or you have weakness, seek professional guidance before starting an exercise programme.
Physiotherapy and Exercises
A physiotherapist may recommend exercises to improve movement, build strength and help you return to everyday activities.
Depending on the diagnosis, a programme may include:
- Gentle mobility exercises
- Strengthening exercises for the trunk and supporting muscles
- Flexibility exercises
- Gradual walking or other appropriate physical activity
- Guidance on lifting, sitting and movement techniques
Exercises should be selected according to the underlying cause and individual symptoms. Stop and seek advice if an exercise causes marked worsening of pain, new numbness or weakness.
Heat or Cold Therapy
A wrapped cold pack or a comfortably warm pack may provide temporary relief for some people.
Avoid placing ice or a hot pack directly against the skin. If you have reduced sensation in the affected area, take extra care because you may not notice skin injury.
These measures can help manage discomfort but do not necessarily resolve the underlying cause of nerve compression.
Medicines for Pain Relief
A clinician may recommend medication based on your symptoms, medical history and other medicines you take.
Anti-inflammatory medicines may help some people, but they are not appropriate for everyone and have potential side effects. The benefits of different medicines for sciatica vary, and some medicines commonly used for nerve pain are not routinely recommended for uncomplicated sciatica.
Do not self-prescribe strong painkillers or begin long-term medication without professional advice.
Injections
In selected cases of severe sciatica, a specialist may consider an injection, such as an epidural corticosteroid injection. The expected benefit, duration of relief, risks and alternatives should be discussed before treatment.
Injections are not necessary for every patient, and their suitability depends on the diagnosis and individual circumstances.
Surgery
Surgery may be considered when there is a clear structural cause of nerve compression and symptoms remain severe despite appropriate non-surgical treatment. It may also be required urgently for certain serious neurological problems.
The procedure depends on the cause. For example, a surgeon may recommend an operation to relieve pressure on a compressed nerve.
Surgery is not routinely required for uncomplicated sciatica. A qualified specialist can explain the potential benefits, risks, recovery process and alternatives.
When Should You See a Specialist for Sciatica?
Consider arranging a medical assessment if:
- Pain travels from your lower back or buttock down your leg.
- The pain interferes with walking, sitting, working or sleeping.
- Symptoms are getting worse or are not improving with appropriate self-care.
- You experience persistent tingling or numbness.
- You have recurring episodes of sciatica.
- You are unsure whether the pain is caused by a spinal or another medical condition.
Depending on the symptoms, an initial assessment may be provided by a general physician. An orthopaedic spine specialist, neurosurgeon, neurologist, physical medicine and rehabilitation specialist or physiotherapist may be involved when appropriate. The right professional depends on the suspected cause and the severity of symptoms.
Sciatica Warning Signs That Need Emergency Care
Seek emergency medical care immediately if you experience any of the following:
- New difficulty starting urination or inability to pass urine
- Loss of bladder or bowel control
- Numbness around the genitals, buttocks or inner thighs
- Severe or rapidly worsening weakness, particularly in both legs
- Severe symptoms affecting both legs, especially with changes in bladder, bowel or saddle-area sensation
These can be signs of a serious condition, such as cauda equina syndrome, that requires urgent assessment. Seek prompt medical advice for sciatica-like pain accompanied by fever, unexplained weight loss, a history of cancer or pain following a significant injury.
Do not wait for a routine appointment if emergency warning signs are present.
How Can You Reduce the Risk of Recurring Sciatica?
Sciatica can return, and it is not always possible to prevent it. However, some habits may support back health and general mobility.
- Stay physically active: Build regular movement into your routine, choosing activities that suit your ability.
- Strengthen supporting muscles: Follow an appropriate programme for your trunk and back muscles if recommended.
- Take breaks from prolonged sitting: Change position and move regularly during long periods at a desk or while travelling.
- Use safe lifting techniques: Keep loads manageable and avoid sudden twisting while lifting.
- Maintain a healthy weight where appropriate: This may help reduce stress on the spine.
- Follow professional advice: If you have recurring symptoms, a clinician or physiotherapist can help identify appropriate changes.
These steps may help support recovery and general back health, but they cannot guarantee that sciatica will not recur.
