Back pain and leg pain are not always the same problem
Pain in the lower back can follow an unfamiliar activity, lifting or bending. Muscles and ligaments can become sore, while changes in the spinal discs or joints may also contribute. There is no single explanation for every painful back, so describing your symptoms is more useful than deciding on a diagnosis yourself. 1
What does sciatica mean?
Sciatica describes symptoms associated with irritation or pressure affecting the sciatic nerve. Pain often travels through the buttock and down one leg, sometimes reaching the foot. Tingling, numbness or weakness may occur. Back pain alone is not the usual sciatica pattern, and a person can have prominent leg symptoms with relatively little back pain. 2
How is the cause assessed?
Your doctor will ask where the pain starts, how long it has lasted and what makes it better or worse. Examination may include movement, strength and sensation. Imaging can help answer particular questions, but the useful test depends on the suspected problem: an X-ray and an MRI show different structures. Not every consultation needs the same scan. 1
Bring previous reports if you have them. A short note about walking, sitting, sleep and any leg symptoms can make the discussion more focused.
What may help while arranging care?
For uncomplicated sciatica, prolonged bed rest is generally discouraged. Gentle movement and continuing tolerable everyday activities can help; an exercise plan should suit your symptoms. Discuss medicines with a clinician or pharmacist rather than assuming every painkiller is appropriate. 2
Treatment may include physiotherapy and other nonsurgical options. Surgery is considered for selected problems after an individual assessment; back pain by itself does not establish that an operation is needed. 1
When is help urgent?
Seek emergency assessment for new difficulty passing urine or loss of bladder or bowel control, numbness around the genitals or bottom, or severe or worsening weakness or numbness affecting both legs. Do not wait for a routine appointment. These can indicate a serious spinal problem. 2
Arrange a consultation if symptoms keep worsening, persist or limit daily activities. Ask what the likely cause is, whether tests would change the plan and which activities are suitable for you. 1, 2
