Sciatica describes pain and sometimes tingling, numbness or weakness associated with irritation or pressure affecting the sciatic nerve. Symptoms may run from the buttock into a leg and foot. It is a symptom pattern, not a complete diagnosis. Finding the cause matters before choosing treatment. MedlinePlus explains sciatica.
When to seek urgent medical help
Go to an emergency department immediately for new difficulty passing urine or loss of bladder or bowel control, numbness around the genitals or anus, or severe or worsening weakness or numbness in both legs. These can signal serious compression of nerves in the lower spine. Do not wait for a routine appointment. The NHS describes these emergency warning signs.
Seek prompt medical care for significant new leg weakness, symptoms after a major injury, or back and leg pain with fever or unexplained weight loss. See MedlinePlus's advice on when to contact a clinician.
How the lower back and leg are connected
A herniated disc and narrowing around the spinal nerves are among the possible causes of sciatic symptoms. The sciatic nerve serves areas of the leg and foot, which helps explain why a problem near the lower spine can be felt farther away. Symptoms can vary in intensity and location. MedlinePlus describes causes and symptoms.
That does not make all leg pain sciatica. Read arm and leg pain for other assessment questions, and disc injury for the difference between an imaging finding and a treatment decision. We do not assume that posture or an everyday bend has put a vertebra out of place.
For back or leg pain during pregnancy, discuss new symptoms with your OB or midwife before choosing treatment.
What an assessment should clarify
Explain where the symptoms travel, whether sensation or strength has changed, and what makes sitting, walking or sleep difficult. Bring prior reports and a list of medicines. Ask the clinician to explain the working diagnosis and any findings that need another provider.
NICE advises against routine imaging in a non-specialist setting for low back pain with or without sciatica. In specialist care, imaging is considered when it is likely to change management. An MRI or x-ray is therefore not an automatic first step for everyone. Read the NICE recommendations.
Care options and their limits
For low back pain with or without sciatica, NICE includes manual therapy only within a plan that includes exercise. The guideline also supports continuing normal activities as appropriate to the person. NICE explains treatment and self-management.
Ask which activities and exercises fit your symptoms now, what changes require reassessment and what progress would justify continuing. A list of stretches online cannot determine the right progression for you.
The research on manipulation specifically for sciatica has limitations. A treatment plan should not promise a painless adjustment, a disc moving back into place or a fixed number of visits that works for everyone. NCCIH summarizes the sciatica evidence.
If spinal decompression is discussed, ask about the evidence, risks and alternatives for your particular findings before deciding. A longer history of symptoms is not by itself a reason to agree to an indefinite course of care.
Risks, alternatives and the next step
Manual care can cause temporary soreness or stiffness. Serious neurological complications have also been reported; an individual's risks depend on their health and the technique. NCCIH explains the safety evidence and its limits. Read the benefits, risks and alternatives to chiropractic care and discuss these before treatment. New or worsening weakness calls for reassessment, not simply more visits.
Physical therapy can help guide an activity and exercise plan. Medical evaluation can clarify whether medicines, specialist assessment or other treatment belongs in your care. The choice should follow the findings and your preferences.

Follow the evidence
Research, with context.
Published sources behind the discussion. Read the findings alongside the limits; a study is not a diagnosis or a promise of a result.
Surgery versus prolonged conservative treatment for sciatica
283 patients with severe sciatica lasting 6–12 weeks, assigned early surgery or prolonged conservative care with surgery if needed.
What it foundEarly surgery provided faster relief and recovery, while one-year outcomes were similar.
What it cannot tell usAbout 39% initially assigned conservative care had surgery. This was not a chiropractic trial and does not show that treatment shrinks discs or guarantees avoiding surgery.

Read the publication recordSystematic literature review of imaging features of spinal degeneration in asymptomatic populations
33 studies reporting imaging findings in 3,110 people without symptoms.
What it foundDegenerative findings were common in people without pain and became more frequent with age. A scan needs interpretation alongside symptoms and examination findings.
What it cannot tell usThis does not mean every disc finding is harmless or that imaging is never needed. It cannot identify the cause of an individual patient’s pain.
