About this condition
Lumbar radiculopathy may cause pain travelling from the lower back down a leg, with tingling or weakness in particular movements. Cervical radiculopathy can spread symptoms from the neck into the shoulder, forearm or fingers. However, not every back or arm pain has a nerve-root cause.
Clinical features
The location, duration and progression of symptoms, any injury and changes in strength are important. A diagnosis cannot be based only on a shooting pain or a degenerative change on a scan. Some spinal imaging findings are common in people without symptoms and must be matched to the examination.
Important differences and warning signs
A clinician assesses reflexes, muscle strength, sensation and relevant neurological signs. MRI is not needed automatically for everyone. It becomes more appropriate when red flags, progressive deficits or a treatment decision make imaging useful.
Assessment and individual care
Initial management is often conservative and individual, focusing on appropriate activity and pain control. Progressive neurological weakness or persistent disabling symptoms may require specialist assessment. Forceful spinal manipulations without evaluation are not a substitute for care.

Signs and symptoms
- Pain spreading from the spine down an arm or leg.
- Numbness, tingling or altered sensation in a particular distribution.
- Sometimes weakness in specific movements or changed reflexes.
Diagnosis and tests
Assessment includes symptoms, strength, reflexes and sensation. MRI and other tests are selected according to clinical indications.
Care and treatment approaches
Individual care may include adapted activity and pain management, with reassessment of neurological function and referral when needed.
When to seek urgent care
New urinary retention, numbness around the saddle area, loss of bowel or bladder control or rapidly worsening weakness can suggest cauda equina syndrome. Seek emergency assessment; call 103 for a severe acute presentation.
Frequently asked questions
Does every pain travelling down a leg mean radiculopathy?
No. Pain can arise from different structures or conditions, and examination helps distinguish them.
Does everyone with radiculopathy need MRI?
No. Imaging depends on red flags, deficits and whether the result would change management.
When is radiating back pain an emergency?
New urinary retention, saddle numbness, loss of bowel control or rapidly progressing weakness requires immediate medical assessment.
