Sciatica vs. Lower Back Pain: How to Tell the Difference and When Physiotherapy Can Help

Pain in the lower back is one of the most common reasons people seek care. But when that pain travels into the buttock or leg, it can be hard to know whether you are dealing with ordinary lower back pain or sciatica. The two can feel similar, but they have different causes, and knowing which one you have helps you choose the right way to recover.

What Is Lower Back Pain?

Lower back pain is discomfort felt in the lumbar region, between the bottom of your ribs and the top of your buttocks. It is often caused by strained muscles, stiff joints, or ligament irritation from lifting, long periods of sitting, poor posture, or sudden movements.

It usually feels like:

• A dull, aching, or tight sensation across the lower back
• Pain that changes with movement, such as bending or twisting
• Stiffness, especially in the morning or after sitting
• Pain that stays mostly in the back, with little or no leg symptoms

What Is Sciatica?

Sciatica is not a diagnosis on its own. It is a set of symptoms caused by irritation or compression of the sciatic nerve, the longest nerve in the body. It runs from the lower back through the buttock and down the back of each leg. Common causes include a herniated disc, spinal stenosis, or tightness in the muscles around the nerve.

Sciatica often feels like:

• Sharp, burning, or shooting pain that travels from the lower back or buttock down one leg
• Tingling, "pins and needles," or numbness in the leg or foot
• Leg weakness
• Pain that gets worse with coughing, sneezing, or prolonged sitting
• Symptoms on one side of the body, rather than both

Key Differences at a Glance

• Location: Lower back pain stays mainly in the back. Sciatica travels into the buttock, leg, or foot.
• Type of pain: Back pain is usually dull and achy. Sciatica is often sharp, electric, or burning.
• Other sensations: Numbness, tingling, and weakness point towards nerve involvement.
• Side: Sciatica typically affects one leg.

It is also possible to have both at the same time, which is why a proper assessment matters.

When to Seek Urgent Medical Care

Most back pain and sciatica improve with the right care. However, go to an emergency department or call your doctor right away if you experience:

• Loss of bladder or bowel control
• Numbness in the groin or inner thighs
• Sudden, severe weakness in one or both legs
• Back pain following a significant fall or accident
• Fever together with back pain

How Physiotherapy Can Help

A physiotherapist can assess your movement, strength, posture, and nerve function to work out what is driving your symptoms. Based on that assessment, treatment may include:

• Manual therapy to ease stiff joints and tight muscles
• Targeted exercises to strengthen the core, hips, and back
• Nerve mobility techniques to reduce irritation along the sciatic nerve
• Posture and movement coaching for sitting, lifting, and daily activities
• A graded return to activity so you can get moving again safely

Staying gently active is generally better than prolonged bed rest, and early physiotherapy can reduce the chance of the problem coming back.

Get Care at Home

With in-home physiotherapy, your assessment and treatment happen in the comfort of your own space, which also lets your physiotherapist look at how you move in your real environment, like your chair, bed, and workspace. If back or leg pain is holding you back, book an appointment and start on a plan built for you.
