At a glance
Back pain describes discomfort in the back. Sciatica describes nerve-related symptoms that often travel into one leg. The pattern can guide an assessment, but it cannot confirm a diagnosis on its own.
- Leg pain, tingling or numbness can suggest nerve involvement.
- A disc finding on a scan is not the same as a diagnosis of sciatica.
- New bladder or bowel changes or severe worsening weakness need emergency care.
Back pain and sciatica: a quick comparison
| Feature | Lower-back pain | Sciatica |
|---|---|---|
| Where symptoms occur | Often centred in the lower back; may spread nearby. | Often travels through the buttock into one leg. |
| How it can feel | An ache, stiffness or discomfort with movement. | Pain with possible tingling, numbness or weakness. |
| What confirms the cause | History and examination; imaging only when indicated. | Clinical assessment of the symptom pattern and nerve function. |
Patterns can overlap; symptoms alone do not establish a diagnosis. Source: NHS sciatica guidance.
What does lower-back pain usually feel like?
Some people experience a stiff, aching lower back after sitting or lifting. Others notice pain when bending, standing or getting up. Pain can sometimes extend into the buttocks without necessarily being sciatica. Causes and contributing factors differ across individuals.
What does sciatica often feel like?
People may describe a line of discomfort running through the buttock or down the back or side of a leg. Tingling, burning, altered sensation or weakness can occur. The pattern matters, but only an examination can assess whether nerve involvement is likely and whether further medical investigations are needed.
Is a disc bulge the same as sciatica?
No. A disc bulge describes an imaging finding. Some people with disc changes have no symptoms, while others may have pain or nerve-related problems. Sciatica describes symptoms, not one specific scan result. Your clinical history and examination help explain whether an imaging finding is relevant.
What happens at a physiotherapy assessment?
A physiotherapist may ask where symptoms travel, what makes them better or worse, whether you have numbness or weakness, and how sleep and activity are affected. Depending on what is appropriate, the examination may include movement, strength, sensation and other neurological checks.
What care options may be discussed?
Some people benefit from staying suitably active, learning which movements are tolerable and progressing an individual exercise plan. A clinician may help with pacing, work modifications and appropriate follow-up. Treatment is not one-size-fits-all, and severe or progressive nerve symptoms may require a medical specialist.
When should you seek emergency medical care?
Do not wait for a routine appointment if you develop new bladder or bowel control problems, difficulty passing urine, numbness around your genitals or saddle area, or severe or worsening weakness/numbness in both legs. These can indicate a serious spinal problem that needs emergency attention. Sudden or rapidly progressive neurological symptoms always deserve urgent evaluation.
Getting support in Bahria Town Phase 7
If you have persistent back discomfort or symptoms that may involve a nerve, you can ask Dr. Arhum Physiotherapy & Pain Clinic about an assessment. Tell the clinic what you are experiencing rather than choosing a diagnosis from a menu. The team can advise on appointment enquiries and whether a medical assessment may be needed first.

Frequently asked questions Can sciatica affect one leg? It commonly does, but symptoms can have different causes and should not be self-diagnosed. Does everyone with sciatica need surgery? No. Management depends on the severity, clinical findings and medical assessment; many people are managed without surgery, while some need specialist care.
