What Is Sciatica?
The sciatic nerve is the largest peripheral nerve in the human body. It is formed from several nerve roots in the lower lumbar and sacral regions of the spine and travels through the buttock and down the back of the leg.
Sciatica is a clinical term used when symptoms follow the distribution of the sciatic nerve, most commonly because a spinal nerve root in the lower back has become irritated or compressed. This is often referred to as lumbar radiculopathy when there are associated neurological symptoms.
A common cause is a herniated or slipped disc, where disc material can irritate a nearby nerve root. Other causes include age-related changes in the lumbar spine, narrowing of the spaces around the nerves (spinal stenosis) and, less commonly, other spinal conditions.
Sciatica can affect one side or, less commonly, both sides. The severity and pattern of symptoms can vary considerably. Some people experience primarily leg pain, while others also have lower back or buttock pain.
Importantly, not every episode of pain travelling into the leg represents sciatica. Conditions involving the hip, buttock or peripheral nerves can produce similar symptoms. A clinical assessment therefore helps establish whether the symptoms are consistent with nerve-root involvement and whether further investigation is appropriate.
What Causes Sciatica?
Sciatica generally develops when a nerve root in the lower spine becomes irritated, inflamed or compressed.
Common causes and contributing factors include:
- Herniated or slipped disc: Disc material can protrude and irritate a nearby nerve root.
- Lumbar spinal stenosis: Narrowing around the spinal canal or nerve-root openings can reduce the available space for spinal nerves.
- Age-related spinal changes: Changes in discs, joints and surrounding bone can sometimes contribute to narrowing or nerve irritation.
- Spondylolisthesis: One vertebra may shift relative to another and contribute to narrowing around a nerve.
- Sudden or repetitive physical loading: Lifting, bending, twisting or other demanding activities may aggravate an already sensitive spinal region.
- Previous episodes of back pain or nerve irritation: Previous symptoms can influence future tolerance to physical loading.
Sciatica is not necessarily caused by one particular movement, posture or activity. Spinal structures change naturally over time, and symptoms often develop through an interaction between structural changes, physical loading, individual capacity and nervous-system sensitivity.
This is also why an abnormality seen on an MRI does not automatically explain the symptoms. Imaging findings need to be considered alongside the person's symptoms and clinical examination.
Common Signs & Symptoms
Sciatica typically produces symptoms along the pathway of a nerve into the buttock and leg. Common symptoms include:
- Pain travelling from the lower back or buttock into the leg
- Sharp, shooting or burning pain
- Tingling or pins and needles
- Numbness
- Leg or foot weakness
- Increased symptoms with certain movements or positions
- Difficulty sitting, standing or walking comfortably
- Changes in normal movement because of pain
- Symptoms that may extend below the knee or into the foot
The exact pattern depends on which nerve root is affected. Some people experience significant leg pain with relatively little back pain, while others have both.
Trivayu's Approach
At Trivayu, we look beyond the label of "sciatica" to understand what is actually happening and how it is affecting you.
Not every person with leg pain has the same presentation. The location of symptoms, neurological findings, aggravating factors and functional limitations can vary significantly. Our assessment therefore considers the relationship between your symptoms, spinal and lower-limb movement, strength and physical demands.
Your rehabilitation is then developed around your individual presentation and goals. This may begin with helping you manage symptoms and remain appropriately active before progressing towards mobility, strengthening, movement retraining and functional loading.
We also recognise that an MRI finding does not determine your recovery on its own. The focus is on what can be meaningfully improved: your movement, physical capacity, confidence and ability to participate in life.
Sciatica physiotherapy in Jaipur at Trivayu Physio Center is focused on managing nerve-related pain, restoring movement and rebuilding strength through personalised rehabilitation.

FAQs
Can physiotherapy help sciatica?
Yes. Physiotherapy can help reduce pain, improve mobility, strengthen supporting muscles and address movement patterns that may be contributing to nerve irritation.
What is the best treatment for sciatica?
Treatment depends on the cause and severity of symptoms, but often includes staying active, targeted exercises, physiotherapy and appropriate pain management.
Can sciatica be treated without surgery?
Yes. Most cases of sciatica are managed without surgery using conservative treatment such as physiotherapy, exercise and activity modification.
What exercises are helpful for sciatica?
Gentle mobility, nerve-related exercises, core strengthening and hip strengthening may help, depending on the cause. Exercises should be chosen according to how your symptoms respond.
Why does sciatica cause leg pain?
Sciatica occurs when a nerve root in the lower back is irritated or compressed, causing pain that can travel through the buttock and down the leg.
Can a slipped disc cause sciatica?
Yes. A herniated or slipped disc can irritate or compress a lumbar nerve root, leading to sciatica symptoms such as leg pain, tingling or numbness.
How long does sciatica take to recover?
Recovery varies, but many people improve over several weeks with appropriate conservative care. More severe or persistent nerve symptoms may take longer to settle.
