Causes of Nerve Pain: What Neuropathic Pain Feels Like, Where It Comes From, and How It Is Treated
Nerve pain called neuropathic pain has a quality that most patients can identify immediately: burning, electric, shooting, or like pins and needles that do not stop. It is different from muscle pain or joint pain in a way that is difficult to describe but instinctively recognisable. It travels. It radiates. It follows a path.
That radiating quality is the key clinical clue. Nerve pain travels along the distribution of the affected nerve, which tells a clinician where in the nervous system the problem originates.
Nerve Pain vs Muscle Pain: An Important Distinction
Feature | Nerve Pain (Neuropathic) | Muscle Pain (Nociceptive) |
|---|---|---|
Quality | Burning, electric, shooting, stabbing | Aching, sore, cramping, dull |
Location | Travels along nerve distribution | Local to the muscle; does not radiate along a path |
Touch sensitivity | Allodynia light touch feels painful | Tender to firm pressure directly on muscle |
Night behaviour | Often worse at night | Variable; often improves with rest |
Response to analgesics | Standard painkillers often ineffective | NSAIDs and paracetamol usually effective |
Specific medications | Gabapentin, pregabalin, amitriptyline | NSAIDs, muscle relaxants |
Distribution | Dermatomal or peripheral nerve territory | Follows muscle anatomy |
Spine-Related Nerve Pain Causes
Sciatica Lumbar Nerve Root Compression
Sciatica is the most common form of nerve pain seen in a spine clinic. It results from compression of one of the lumbar nerve roots most often at L4/L5 or L5/S1 as it exits the spinal canal.
The herniated disc pushes against the nerve root, which carries pain signals along the entire length of the nerve. The brain perceives pain along that nerve’s route into the leg, even though the source of compression is in the spine. The result is burning or electric pain running from the lower back through the buttock, down the back or side of the leg, and into the foot.
The pain quality is typically intense and radiating. It worsens with sitting, which increases disc pressure, and often partially eases with walking. Bending forward frequently makes it worse.
Cervical Radiculopathy Neck Nerve Root Compression
A cervical disc herniation compresses a nerve root exiting the neck, producing burning or electric pain radiating down the arm into specific fingers. The pattern is specific to the level compressed: C5/C6 sends pain toward the thumb and index finger; C6/C7 produces middle finger symptoms.
Turning the head or looking upward may worsen the arm pain. Numbness and tingling follow the same distribution as the pain.
Spinal Stenosis and Neurogenic Claudication
Narrowing of the spinal canal at multiple lumbar levels compresses nerve roots broadly. Rather than a single nerve root pattern, patients experience bilateral leg aching, burning, and heaviness that comes on with walking and is relieved by sitting or leaning forward. The leg pain with walking that eases with rest is called neurogenic claudication.
Peripheral Nerve Causes
Diabetic Peripheral Neuropathy
Chronic high blood sugar damages the small fibres in peripheral nerves, producing a diffuse burning, tingling, and numb quality starting in the feet and progressing upward. The distribution is symmetrical with both feet equally, both hands equally. In the UAE, where diabetes prevalence is high, this is among the most common causes of leg nerve pain.
Post-Herpetic Neuralgia
Following shingles reactivation of the varicella zoster virus, severe burning pain persists along the affected dermatome after the rash has healed. This can persist for months to years and is one of the most debilitating forms of neuropathic pain. Most commonly affects the thoracic region.
Carpal Tunnel Syndrome Median Nerve
Compression of the median nerve at the wrist produces burning, tingling, and pain in the thumb, index, and middle fingers. Characteristically worse at night and with prolonged wrist flexion. Pain may radiate up the forearm.
Piriformis Syndrome
The piriformis muscle in the buttock can compress the sciatic nerve as it passes beneath or through it, producing sciatic-distribution leg pain mimicking disc-related sciatica. The absence of disc herniation on MRI with characteristic buttock tenderness and pain worsening with prolonged sitting raises this possibility.
L4, L5, S1 Nerve Pain Distributions
Nerve Root | Pain Distribution | Weakness | Reflex Affected |
|---|---|---|---|
L4 | Front of thigh, inner shin to big toe | Knee extension (quadriceps) | Knee jerk |
L5 | Outer thigh, outer shin, top of foot and big toe | Foot dorsiflexion (foot drop) | Variable |
S1 | Back of thigh, calf, outer foot and heel | Plantarflexion (toe raise) | Ankle jerk |
When an MRI Is Needed for Nerve Pain
- Leg or arm nerve pain not improving after four to six weeks of conservative management
- Neurological deficit developing alongside nerve pain weakness, reflex loss, foot drop
- Bilateral leg nerve pain both legs affected, suggesting central canal stenosis
- Nerve pain following a history of malignancy spinal metastasis must be excluded
- Bladder or bowel symptoms alongside leg nerve pain emergency MRI
How Nerve Pain Is Diagnosed
- Clinical examination: maps the distribution of pain, identifies dermatomal pattern, assesses reflexes and power
- Nerve Conduction Study (NCS): measures conduction velocity in peripheral nerves; identifies peripheral neuropathy and carpal tunnel syndrome
- EMG: assesses muscle electrical activity; identifies which nerve root or peripheral nerve is affected
- MRI Spine: identifies disc herniation, spinal stenosis, or cord compression as a structural cause
- Blood tests: HbA1c for diabetes, B12, inflammatory markers
Treatment for Nerve Pain
Medications
Standard analgesics paracetamol and NSAIDs are often insufficient for neuropathic pain. Medications specifically targeting nerve pain are:
- Gabapentin and pregabalin: reduce nerve hypersensitivity; effective for radiculopathy and peripheral neuropathy
- Amitriptyline and duloxetine: antidepressants with established nerve pain efficacy
- Topical agents: lidocaine patches and capsaicin cream for localised peripheral nerve pain
Interventional Treatments
- Epidural steroid injection: delivers anti-inflammatory medication directly adjacent to the compressed nerve root; effective short-term for radiculopathy
- Selective nerve root block: targets a specific nerve root under fluoroscopic or CT guidance
Surgery
When nerve pain results from a surgically correctable structural cause a herniated disc compressing a nerve root, spinal stenosis causing neurogenic claudication, or carpal tunnel syndrome surgery provides reliable relief that medications and injections cannot achieve long-term.
Microdiscectomy for sciatica, decompressive laminectomy for stenosis, and carpal tunnel release for median nerve compression are the most common procedures. The decision to proceed with surgery is based on severity of symptoms, degree of neurological deficit, and failure of adequate conservative treatment.
Should I See a Neurologist or Neurosurgeon for Nerve Pain?
A neurologist manages the medical workup and non-surgical treatment of nerve pain. A neurosurgeon is the appropriate specialist when a structural, surgically correctable cause has been identified on imaging, when neurological deficits are developing, or when conservative treatment including injection has not provided adequate relief.
For many patients, the correct pathway begins with a GP referral to a neurologist, who arranges nerve conduction studies and imaging. If a surgical cause is found, a neurosurgical opinion follows.
Conclusion
Nerve pain has a distinctive burning, electric, radiating character that sets it apart from other pain types. Identifying where in the nervous system the problem originates from the peripheral nerve, nerve root, spinal cord, or brain determines both the investigation and the treatment. Many causes are treatable, and surgical decompression reliably resolves nerve pain when a structural cause is identified and corrected.

Frequently Asked Questions
Nerve pain is typically described as burning, electric, shooting, or stabbing in quality. It often radiates along a specific path down the leg in sciatica, or down the arm in cervical radiculopathy. Light touch may feel painful or unpleasant (allodynia). It is often worse at night. The travelling, radiating quality distinguishes it from localised muscle pain.
Burning pain in the legs has several causes. Lumbar radiculopathy from a herniated disc compresses a nerve root, producing burning pain radiating from the back down into the leg. Peripheral neuropathy most commonly from diabetes or B12 deficiency produces symmetrical burning starting in the feet. Spinal stenosis causes bilateral leg burning with walking. The distribution and pattern help identify the cause.
Yes. A herniated lumbar disc compresses a nerve root as it exits the spine, producing the electric, burning, radiating pain of sciatica. The pain follows the path of that nerve down into the leg. A herniated cervical disc similarly compresses a nerve root in the neck, producing radiating arm pain. Disc-related nerve pain is one of the most common causes of severe radicular pain in adults.
MRI is indicated when nerve pain has not improved after four to six weeks, when neurological deficits such as weakness have developed, when both legs are symptomatic simultaneously, when there is a history of cancer, or when bladder or bowel symptoms accompany leg pain. MRI of the spine identifies the structural cause of disc herniation, stenosis, or tumour that is driving the nerve pain.
Diagnosis begins with a clinical history identifying the quality, distribution, and pattern of pain. Neurological examination assesses reflexes, power, and sensation. Nerve conduction studies and EMG measure nerve function directly. MRI of the spine identifies structural causes. Blood tests including HbA1c and B12 exclude metabolic and nutritional causes of peripheral neuropathy.
Start with a neurologist for investigation and medical management. A neurologist will arrange nerve conduction studies, identify the pattern of involvement, and manage medications. If imaging reveals a structural surgical cause of a herniated disc compressing a nerve root, spinal stenosis, or carpal tunnel a neurosurgical opinion follows. Both specialties work together for complex nerve pain presentations.
