Explore symptoms, assessment and rehabilitation considerations for leg pain.
Sciatica can cause pain, tingling or numbness travelling from the buttock down a leg, sometimes into the foot. Staying active and tailored rehabilitation may help, but new neurological symptoms need assessment. This guide explains home care, exercise planning and when to seek medical help.
Symptoms and assessment of sciatica
The NHS sciatica guide describes irritation or compression of the sciatic nerve pathway. Symptoms commonly affect one leg and may include burning pain, tingling, numbness or weakness. Back pain alone does not necessarily mean sciatica.
Tell a clinician where symptoms travel, when they began and whether strength or sensation has changed. An assessment helps decide what care is appropriate; pain location alone cannot identify the cause.
When sciatica needs emergency care
Seek emergency care for symptoms on both sides, severe or worsening weakness or numbness in both legs, or numbness around the genitals or bottom. New difficulty starting urination, inability to urinate, loss of bladder control, or loss of bowel sensation or control also needs emergency assessment.
These are warning signs listed in the NHS guidance and should not wait for a physiotherapy appointment or an exercise trial. Arrange medical review if symptoms are worsening, limiting usual activities or not improving with home care.
Home care and activity pacing
NICE recommends advice tailored to your needs and encouragement to continue normal activities. Prolonged inactivity is generally unhelpful. Choose manageable amounts of movement and discuss limits if symptoms interfere with walking, work or sleep.
The Guy's and St Thomas' activity-pacing guidance describes breaking tasks into smaller parts, taking rests and gradually building activity from what you currently manage.
For example, record how far you can walk and what happens to leg symptoms afterwards. Bring that information to your consultation so the next step reflects your response rather than a fixed weekly increase. Ask a pharmacist or clinician about suitable pain relief instead of choosing medicines from an exercise guide.
Choosing exercises for sciatica
NICE advises taking your needs, preferences and capabilities into account when choosing exercise for low back pain with or without sciatica. There is no single stretch, nerve glide or strengthening routine that this guide can prescribe for every presentation.
A physiotherapist can discuss which movements feel manageable, your daily demands and whether the plan should include mobility, strengthening or general fitness. Ask how to monitor symptoms and when to pause or adapt a movement.
Do not force a stretch that increases leg symptoms. Report new or worsening weakness or sensory changes promptly; use emergency care for the warning signs above.
Preparing for physiotherapy
Bring any previous assessment reports and describe goals such as walking to work, sitting through a meeting or returning to exercise. Explain what you have tried and how symptoms responded. Agree on follow-up points to review function and the plan.

Common questions about sciatica
Do I need an MRI before starting care?
NICE does not recommend routine imaging in a non-specialist setting. A specialist may consider a scan if the result is likely to change treatment. That does not remove the need to assess urgent symptoms.
Can recovery be guaranteed by a particular week?
No. Review your symptoms and function with a clinician. Recurring or persistent symptoms may need a change in care rather than repeating the same home routine.
