If you’ve ever felt a nagging ache in your lower back after hours of sitting, or a sharp, shooting pain that travels down your leg, you might have wondered if they’re the same problem. Many people lump both experiences under the umbrella of “back pain.” In reality, lower back pain and sciatica are related but distinct conditions.
This confusion is widespread. Both affect the same region, both can make even simple activities — like bending, sitting, or walking — difficult, and both are increasingly common in India’s working population. However, knowing the difference between the two is critical, because the underlying causes and treatment approaches often differ.
In this blog, we’ll explore what sciatica and lower back pain actually mean, how to tell them apart, why they sometimes overlap, and the best ways to manage and prevent them. By the end, you’ll have the clarity you need to better understand your spine health and when to seek medical help.
Understanding Lower Back Pain
What Is Lower Back Pain?
Lower back pain (LBP) is one of the most common health complaints globally. The World Health Organization (WHO) estimates that up to 70% of adults will experience back pain at some point in their lives. In India, studies show that nearly one in five adults suffer from chronic low back pain.
Lower back pain is not a disease in itself; rather, it is a symptom that can result from multiple underlying issues. It can range from mild stiffness to severe, disabling pain.
Types of Lower Back Pain
Medical professionals usually divide lower back pain into categories:
- Mechanical Back Pain – Stemming from muscles, ligaments, joints, or spinal structures. This is the most common type.
- Inflammatory Back Pain – Associated with autoimmune conditions like ankylosing spondylitis.
- Referred Pain – When pain from another organ (like the kidneys or pancreas) is felt in the lower back.
Common Causes
Some of the most frequent triggers of lower back pain include:
- Muscle or ligament strain due to heavy lifting or awkward movement.
- Degenerative disc disease and age-related changes.
- Herniated discs, which may or may not cause nerve symptoms.
- Spinal stenosis, a narrowing of the spinal canal.
- Poor posture and prolonged sitting.
- Fractures due to osteoporosis in older adults.
Symptoms of Lower Back Pain
- Dull or aching pain localized to the lumbar area.
- Stiffness, especially after rest.
- Pain that worsens with sitting or standing for long periods.
- Limited flexibility.
- Muscle spasms.
Understanding Sciatica
What Is Sciatica?
Sciatica refers to pain caused by irritation or compression of the sciatic nerve — the longest nerve in the body, running from the lower spine down through the buttocks, thighs, calves, and feet.
Unlike generalized back pain, sciatica follows a clear nerve pathway and is usually one-sided.
Causes of Sciatica
- Herniated or slipped disc pressing on the nerve.
- Lumbar spinal stenosis narrowing nerve spaces.
- Bone spurs due to arthritis.
- Spondylolisthesis (vertebral slippage).
- Piriformis syndrome, where a small muscle in the buttocks irritates the sciatic nerve.
Symptoms of Sciatica
- Sharp, shooting pain radiating down one leg.
- Tingling, pins-and-needles sensation.
- Numbness or weakness in the leg or foot.
- Pain aggravated by coughing, sneezing, or long sitting.
- Typically affects only one side of the body.
Symptoms often worsen when sitting, bending, or coughing, and may improve when lying down.
Diagnosis: How Doctors Confirm a Herniated Disc
Diagnosis combines medical history, physical exam, and imaging tests:
1. Physical Examination
- Checking reflexes, muscle strength, walking ability, and sensation.
- Straight leg raise test for lumbar herniation.
2. Imaging Tests
- MRI: Gold standard for identifying herniation and nerve compression.
- CT Scan: Helpful when MRI isn’t possible.
- X-ray: Rules out other spine problems but doesn’t show discs.
3. Nerve Tests
- Electromyography (EMG): Measures electrical activity of muscles.
- Nerve conduction studies: Show how well electrical signals travel.

Summary: All sciatica involves back pain, but not all back pain is sciatica.
Why People Confuse the Two
- Both start in the lower back region.
- Both can make walking or sitting painful.
- Disc problems can cause either or both.
- In early stages, pain may feel similar before radiation sets in.
The Impact of Lifestyle on Both
Sedentary Jobs
Office workers sitting for 8–10 hours a day are at high risk. Poor ergonomics and lack of movement weaken spinal muscles and increase disc pressure.
Heavy Physical Labor
In rural India, farmers and laborers often develop back pain or disc injuries due to repetitive heavy lifting.
Obesity
Excess body weight adds load to the lumbar spine, worsening both conditions.
Vitamin D Deficiency
Widespread in India, this weakens bones and contributes to disc problems.
How Sitting Too Long Affects the Spine
- Increases spinal disc pressure by up to 40% compared to standing.
- Weakens core muscles.
- Stiffens hip flexors, pulling on the spine.
- Increases risk of disc herniation.
A Harvard Health study shows that microbreaks and movement reduce back pain by improving circulation and reducing muscle fatigue.
Diagnosis: How Doctors Differentiate
Physical Examination
- Straight Leg Raise (SLR) Test for sciatica.
- Palpation of muscles and movement tests for general back pain.
Imaging
- X-rays to rule out fractures.
- MRI for disc herniation or stenosis.
- CT scan if MRI isn’t possible.
Nerve Tests
- Electromyography (EMG) can confirm nerve irritation in sciatica.
Treatment Approaches
Conservative Treatments (Both Conditions)
- Rest (short term only).
- Heat or ice therapy.
- NSAIDs (non-steroidal anti-inflammatory drugs).
- Physiotherapy and guided exercise.
- Ergonomic corrections at workplace/home.
Sciatica-Specific Treatments
- Epidural steroid injections.
- Nerve mobilization techniques.
- Surgery (like microdiscectomy) for severe cases.
Lower Back Pain-Specific Treatments
- Core strengthening for stabilization.
- Lifestyle modification (weight loss, posture training).
- Alternative therapies (yoga, acupuncture, though evidence varies).
Prevention Strategies
At Work
- Take a break every 30–45 minutes.
- Adjust chair height so feet rest flat.
- Keep screens at eye level.
At Home
- Sleep on a medium-firm mattress.
- Exercise regularly (swimming, walking, yoga).
- Avoid lifting with the back — bend at the knees instead.
Nutrition
- Adequate calcium and vitamin D intake.
- Stay hydrated to maintain disc health.
When to Seek Medical Help
See a doctor immediately if you experience:
- Sudden, severe pain after trauma.
- Weakness or numbness in the leg.
- Loss of bladder or bowel control (medical emergency).
- Pain persisting longer than 6 weeks despite self-care.
The Indian Burden of Back Pain and Sciatica
- According to The Lancet, low back pain is the leading cause of disability worldwide.
- In India, it affects both urban professionals and rural workers.
- Lack of awareness often delays treatment, worsening outcomes.
Role of We Are Spine
At We Are Spine, the focus is on accurate diagnosis and evidence-based treatment of spinal conditions like lower back pain and sciatica. The team emphasizes non-surgical management first, including physiotherapy, ergonomic counseling, and lifestyle correction. When surgery is unavoidable, minimally invasive techniques are used to ensure faster recovery and improved outcomes. The aim is to restore mobility, reduce pain, and improve quality of life for every patient.
Conclusion
Lower back pain and sciatica are often confused, but they are not the same. Lower back pain is a broad term that can stem from muscles, ligaments, discs, or bones, while sciatica specifically refers to irritation of the sciatic nerve, usually from a disc problem.
Understanding the difference helps patients seek appropriate care sooner, preventing chronic pain and complications. With the right lifestyle habits, ergonomic practices, and medical guidance, both conditions can be managed effectively.
Taking care of your spine today means a healthier, more active tomorrow.
