About this symptom
Pain from the neck or lower back may travel into the arm, buttock or leg, sometimes with tingling, altered sensation or weakness. A clinician considers whether a nerve root may be irritated, but the pain pattern alone does not prove a disc herniation.
Clinical features
The relationship to movement, coughing and posture, the duration of symptoms and any genuine loss of strength help guide assessment. The neurological examination checks reflexes, sensation and strength. In the absence of red flags, routine imaging at the first visit may not change management.
Important differences and warning signs
MRI is considered when neurological deficits, progression or a potential change in treatment justify it. An abnormality on a scan may not be the actual cause of symptoms, so images must be interpreted alongside examination findings.
Assessment and individual care
Without dangerous features, care commonly involves maintaining tolerable activity, individual exercise, suitable pain management and follow-up. Injections, nerve blocks and operations are not automatic treatments for everyone with radiating back pain.

Signs and symptoms
- Pain spreading from the neck or lower back to an arm, buttock or leg.
- Tingling, numbness or shooting pain, sometimes with a loss of muscle strength.
- Possible worsening with particular movements, coughing or changing posture.
Diagnosis and tests
Assessment focuses on strength, reflexes, sensation and warning signs. MRI is ordered when there are clinical reasons for imaging rather than as a routine response to all back pain.
Care and treatment approaches
Appropriate activity, rehabilitation exercises and individual pain relief may be discussed when red flags are absent. Procedures are not universally required.
When to seek urgent care
New urinary retention, loss of bowel control, numbness around the groin or saddle area, or rapidly worsening leg weakness may indicate cauda equina syndrome. Call 103 for emergency care.
Frequently asked questions
Does radiating pain always mean a slipped disc?
No. There are several possible causes, and scan findings do not always explain symptoms.
Does everyone with this pain need an MRI?
No. Routine imaging is often unnecessary when examination reveals no red flags or progressive neurological problems.
Which symptoms require immediate help?
New difficulty passing urine, loss of bowel control, saddle numbness or rapidly increasing weakness are emergencies.
