Peripheral Nerve Pain
Burning, tingling, numbness, or pain related to nerves outside the brain and spinal cord.
Overview
Peripheral nerves carry signals between the spinal cord and the rest of the body. When one is compressed, injured, or inflamed outside the spine, the result is often a distinctive type of pain: burning, electric, sharp, or accompanied by tingling and numbness in the territory that nerve serves.
Peripheral nerve pain overlaps with spine-related nerve pain in how it feels, but the causes and treatments differ. Nerves can be entrapped at narrow passages, such as the wrist or the outer knee, injured during surgery or trauma, irritated after direct pressure, or affected by broader medical conditions such as diabetes. Identifying which pattern applies is the essential first step.
Symptoms
- Burning, electric, or shooting pain in a specific territory
- Tingling or pins-and-needles sensations
- Numbness in the distribution of a single nerve
- Sensitivity to touch or pressure in the affected area
- Occasional weakness in muscles served by the nerve
- Symptoms that do not follow the patterns typical of spine-related pain
Possible causes
Entrapment at anatomic narrow points, direct injury or trauma, surgical nerve injury, prolonged pressure, metabolic conditions including diabetes and thyroid disorders, inflammatory conditions, and certain medications can all affect peripheral nerves. Sometimes the cause remains uncertain even after evaluation.
How it is diagnosed
History and neurologic examination map symptoms against each nerve's known territory. Electrodiagnostic testing (EMG and nerve conduction studies) is often central, since it can localize the problem to a specific nerve and distinguish entrapment from spine-related causes. Imaging and laboratory evaluation may contribute depending on the picture. When appropriate, targeted diagnostic blocks may use fluoroscopy/X-ray guidance to assist needle placement.
Treatment options
Treatment depends on the cause. Entrapments may respond to activity modification, splinting, rehabilitation, or targeted injection. Nerve-related pain can be managed with appropriate medication review. Persistent or clearly localized problems are situations where peripheral nerve blocks or other targeted procedures are considered. Underlying medical conditions, when present, are managed in coordination with your other physicians.
When to see a specialist
Evaluation is appropriate for persistent burning or tingling, numbness that does not resolve, symptoms that disrupt sleep, or any weakness. It is especially worthwhile when prior treatment aimed at the spine has not helped, since that may indicate the nerve problem is peripheral rather than spinal.
