Sciatica pain can affect people differently. Some patients experience pain while standing or walking, while others feel intense pain mainly when they sit.

Many patients describe their experience like this:

“My sciatica was caused by a herniated disc. The pain was at its worst whenever I sat down. It was a sharp, intense pain travelling through my leg. Driving, working or simply relaxing became difficult. Standing and walking were usually manageable and sometimes even provided relief.”

As a neurosurgeon and spine specialist, Dr. Vishal Bhasme commonly sees patients with this type of pain pattern. In many cases, the underlying cause is a herniated disc irritating or compressing a nerve in the lower back.

What Is Sciatica?

Sciatica is pain caused by irritation or compression of the sciatic nerve or one of the nerve roots that forms it. The sciatic nerve begins in the lower spine and travels through the buttocks and down the legs.

Sciatica is not a separate disease. It is a symptom of an underlying spinal condition.

Common symptoms include:

• Sharp or shooting pain in one leg
• Pain travelling from the buttock to the thigh or calf
• Burning or electric-shock-like sensations
• Tingling or pins and needles
• Numbness in the leg or foot
• Weakness in the affected leg
• Pain that worsens while sitting, coughing or sneezing

Sciatica usually affects one side of the body. Some patients experience severe leg pain even when their back pain is mild or completely absent.

If the symptoms include pain, numbness or tingling travelling into the leg, it may help to understand the common symptoms of a pinched nerve in the lower back.

How Does a Herniated Disc Cause Sciatica?

The bones of the spine are separated by soft cushions called spinal discs. These discs absorb pressure and allow the spine to move comfortably.

A herniated disc develops when the soft material inside a disc pushes through a weak area in its outer layer. The displaced material may compress or irritate a nearby spinal nerve.

This can cause pain to travel from the lower back into the:

• Buttock
• Back or side of the thigh
• Calf
• Ankle
• Foot or toes

The location of the pain depends on which spinal nerve is affected. A herniated disc can also cause inflammation around the nerve, which means that even a relatively small disc herniation may sometimes produce significant pain.

Why Is Sciatica Pain Worse While Sitting?

Sitting changes the position of the lower spine and can place additional pressure on the lumbar discs. This is especially noticeable when a person sits with a rounded back or leans forward for a long time.

If a herniated disc is already irritating a nerve, sitting may increase the irritation and cause sharp pain to travel down the leg.

Several factors can make sciatica worse while sitting:

Increased pressure on the lower-back discs

Pressure on the lumbar discs may increase while sitting, particularly when the lower back is unsupported.

Poor sitting posture

Slouching, leaning forward or sitting to one side may place additional strain on the lower spine.

Staying in one position

Sitting without changing position can cause stiffness and make the irritated nerve more sensitive.

Low or soft seating

Soft sofas and low chairs may allow the pelvis to sink backwards, causing the lower back to become rounded.

Driving posture

Driving can be especially painful because the hips remain bent, the legs stay extended towards the pedals and the body remains in one position. Road vibrations may also aggravate the symptoms in some patients.

Why Does Standing or Walking Sometimes Feel Better?

Standing or gentle walking changes the position of the spine and prevents the body from remaining still for too long. Movement may reduce stiffness and ease irritation around the affected nerve.

However, every patient’s pain pattern is different. Some spinal conditions, such as lumbar spinal stenosis, may cause pain while standing or walking and relief while sitting or bending forward.

The pattern of pain can provide an important clue, but it cannot confirm the diagnosis by itself. A proper neurological examination is required to determine the exact cause.

How Is the Cause of Sciatica Diagnosed?

During a consultation, Dr. Vishal Bhasme will generally assess:

• Where the pain begins and how far it travels
• Which positions increase or reduce the pain
• Whether numbness, tingling or weakness is present
• How long the symptoms have continued
• Whether the pain affects driving, working, walking or sleeping
• Whether bladder or bowel changes are present

A neurological examination may be performed to assess muscle strength, sensation and reflexes. Tests such as the straight leg raise can also help identify nerve irritation.

An MRI of the lumbar spine may be recommended when symptoms are severe, continue despite treatment or are accompanied by weakness or numbness.

However, treatment should not be decided based only on an MRI report. Some people have a disc bulge on their scan without experiencing significant symptoms. Learn more about whether a disc bulge seen on an MRI requires spine surgery.

How Can You Sit More Comfortably with Sciatica?

The following changes may help reduce discomfort:

• Use a firm and supportive chair.
• Keep both feet flat on the floor.
• Keep the hips level with or slightly higher than the knees.
• Place a small cushion or lumbar roll behind the lower back.
• Avoid slouching or leaning to one side.
• Do not sit continuously for long periods.
• Stand up and walk briefly at regular intervals.
• Avoid keeping a wallet or bulky object in your back pocket.
• Adjust your car seat so you can reach the pedals without leaning forward.
• Avoid very low chairs and excessively soft sofas.

Maintaining good posture and staying active can also protect the spine over time. These practical tips on how to prevent low back pain as you age may be helpful.

These suggestions may provide temporary relief, but they do not replace medical evaluation. Stop any movement or exercise that causes the pain to become more severe or travel further down the leg.

Does Every Herniated Disc Require Surgery?

No. Finding a herniated disc on an MRI does not automatically mean that surgery is required.

Many patients improve with non-surgical treatment, which may include:

• Activity modification
• Doctor-prescribed medicines
• Physiotherapy
• Posture correction
• Supervised exercises
• Heat or cold therapy when appropriate
• Epidural injections in selected cases

Complete bed rest is generally not recommended. Staying inactive for a long time may increase stiffness and delay recovery. Patients are usually encouraged to remain gently active within comfortable limits.

The treatment plan should be personalised because the same exercise, activity or sitting position may not suit every patient.

When Is Spine Surgery Considered?

Spine surgery may be considered when:

• Severe leg pain continues despite appropriate treatment
• Pain significantly affects work, sleep or daily activities
• Numbness or muscle weakness is worsening
• The patient finds it difficult to stand or walk
• Symptoms repeatedly affect quality of life
• MRI findings clearly match the symptoms
• Bladder or bowel function is affected

Depending on the location and type of disc herniation, different surgical procedures may be considered.

Microdiscectomy

A microdiscectomy removes the portion of the herniated disc that is pressing on the nerve. It may be considered when persistent nerve compression causes severe leg pain, numbness or weakness.

Learn more about microdiscectomy surgery for back and leg pain.

Endoscopic spine surgery

In selected patients, endoscopic spine surgery may allow the surgeon to treat the compressed nerve through a small incision with minimal disturbance to the surrounding muscles and tissues.

Read about endoscopic spine surgery in Pune and the conditions for which it may be considered.

Surgery is recommended only when it is medically necessary and likely to provide meaningful relief.

When Should You Seek Emergency Medical Care?

Seek urgent medical attention if sciatica is accompanied by:

• Loss of bladder or bowel control
• Difficulty starting or controlling urination
• Numbness around the genitals, inner thighs or buttocks
• Severe or worsening weakness in the legs
• Symptoms affecting both legs
• Sudden difficulty standing or walking

These may be warning signs of serious nerve compression and should not be ignored. You can also review the important back pain red-flag symptoms that require medical attention.

Consult Dr. Vishal Bhasme for Sciatica Treatment in Pune

If sharp leg pain becomes worse while sitting, a herniated disc may be irritating a nerve in the lower spine. The pain can make driving, desk work and even resting extremely uncomfortable, while standing or gentle walking may feel comparatively easier.

A detailed neurological examination can help determine whether the symptoms are caused by a herniated disc, pinched nerve or another spinal condition.
