Back pain and sciatica are often confused — and for good reason. Sciatica frequently starts as back pain before progressing into the leg. But the distinction matters, because the treatment approach differs. Here’s how to tell whether your back pain is run-of-the-mill or something more specifically sciatic.
1. The Pain Travels Down One Leg
This is the hallmark of sciatica. While ordinary back pain tends to stay in the lower back or occasionally spread across both buttocks, sciatic pain follows a predictable path — down one side of the body, through the buttock, into the back of the thigh, and often as far as the calf or foot.
The pain follows the path of the sciatic nerve, which exits the lumbar spine and travels through the buttock and down the leg. If your pain consistently travels down one leg, sciatica is the most likely diagnosis.
2. The Pain Feels Sharp, Burning, or Electric
Ordinary muscle pain in the back tends to feel dull, achy, or cramping. Sciatic nerve pain, by contrast, is often described as sharp, burning, shooting, or electric — like a bolt of lightning running down the leg. Some people describe it as a hot poker. If your pain has this quality, it strongly suggests nerve involvement.
3. You Have Numbness or Tingling in the Leg
When the sciatic nerve is compressed or irritated, it can cause changes in sensation along its path. You might experience numbness, pins and needles, or tingling in the buttock, thigh, calf, or foot. Sometimes specific areas go numb — for example, the top of the foot or the outer calf — corresponding to which nerve root is affected.
4. Sitting Makes It Worse
Prolonged sitting increases pressure on the lumbar discs and sciatic nerve roots. If your pain gets significantly worse when you sit — particularly in the car — and eases when you walk or lie flat, that’s a classic sciatica pattern.
The piriformis muscle, which the sciatic nerve passes near (or through, in some people), is also compressed by sitting. If the piriformis is the culprit, sitting on hard surfaces may be especially aggravating.
5. Coughing or Sneezing Causes a Jolt of Pain
Actions that increase pressure inside the spinal canal — coughing, sneezing, straining on the toilet — momentarily increase pressure on a herniated disc or inflamed nerve root. If you notice a sharp jolt of pain down your leg when you cough or sneeze, this is a strong sign of disc-related sciatica.
6. You Feel Weakness in the Leg or Foot
Sciatic nerve compression doesn’t just cause pain — it can also affect motor function, causing weakness in the muscles the nerve supplies. You might notice difficulty lifting the front of your foot (foot drop), weakness in the calf when rising on tiptoes, or an overall sense that the leg feels unreliable or heavy.
Any leg weakness alongside back and leg pain warrants prompt physiotherapy assessment.
7. One Side Is Always Worse
True sciatica is almost always one-sided. If you have bilateral leg pain or symptoms that shift between legs, the diagnosis may be different — spinal stenosis, cauda equina syndrome (a medical emergency), or hip-referred pain. If you have severe bilateral leg symptoms, loss of bladder or bowel control, or saddle anaesthesia (numbness in the groin), seek emergency medical care immediately.
What Should You Do If You Have Sciatica?
The good news: most sciatica resolves with the right treatment. Evidence consistently supports physiotherapy as the first-line treatment for sciatica — not rest, not surgery (in the vast majority of cases), not simply waiting for it to pass.
At Burwood Physio, our approach to sciatica treatment includes:
- Manual therapy to reduce joint and disc pressure on the nerve
- Neural mobilisation (nerve flossing) to reduce nerve sensitivity
- McKenzie exercises for disc-related sciatica
- Dry needling to the piriformis and gluteal muscles for piriformis syndrome
- Core stabilisation to protect the lumbar spine long-term
Most patients with acute sciatica see significant improvement within 4–6 weeks. Read more on our Sciatica Treatment page.
When to See a Doctor Urgently
While most sciatica is managed safely with physiotherapy, the following symptoms require immediate medical attention:
- Loss of bladder or bowel control
- Numbness in the inner thighs, groin, or genitals
- Rapidly progressive leg weakness affecting both legs
- Severe pain following significant trauma
