Quick Insights:
Neuropathic pain arises from damaged or malfunctioning nerves that send abnormal pain signals to your brain. Unlike injury-related pain that fades as tissues heal, nerve pain persists because the nervous system itself becomes hypersensitive. Damaged nerves fire spontaneously, creating burning, tingling, or electric-shock sensations even without ongoing tissue damage. This distinct mechanism explains why standard pain medications often provide limited relief. Persistent nerve pain requires specialized evaluation to identify the underlying nerve dysfunction and guide targeted treatment approaches.
Key Takeaways:
- Nerve damage triggers microglial activation in the spinal cord, amplifying pain signals through neuroinflammatory cascades.
- Central sensitization causes your nervous system to interpret normal sensations as painful, perpetuating chronic symptoms.
- Standard analgesics target tissue inflammation, not the neural circuit changes that drive neuropathic pain.
- Neuromodulation therapies can reduce pain by modulating dorsal root ganglia and spinal cord circuits directly.
Why It Matters:
Understanding that your burning, tingling pain stems from nerve dysfunction—not ongoing tissue damage—helps explain why conventional treatments may have failed. This knowledge empowers you to seek specialized care that targets the neural pathways driving your symptoms. Mechanism-informed interventions may restore function, improve sleep, and help you return to daily activities that chronic nerve pain has limited.
Introduction
As a double board-certified pain physician serving Napa and surrounding communities, I've treated hundreds of patients whose burning, tingling pain never responded to standard medications. As Dr. Jacqueline Weisbein, DO, my expertise extends to exploring the unique mechanisms that set neuropathic pain apart from other pain types.
A 2006 comprehensive review found that nerve injury triggers central sensitization, microglial activation, and dorsal root ganglion changes—mechanisms fundamentally different from the inflammatory pathways that drive typical injury pain. This explains why anti-inflammatories and opioids often fall short.
In my Napa practice, I perform advanced neuromodulation procedures that target these specific neural circuits. Understanding that your pain arises from malfunctioning nerve pathways—not ongoing tissue damage—opens the door to interventional options designed to modulate those circuits directly.

This article explains why neuropathic pain behaves so differently and what that means for your treatment path.
What Makes Neuropathic Pain Different: Insights for Napa Residents
Neuropathic pain originates from damaged nerves rather than injured tissues. When you sprain your ankle or strain a muscle, pain signals travel from the injury site to your brain, then fade as healing progresses. Nerve pain works differently—the nervous system itself becomes the problem.
In my practice, I evaluate Napa-area patients whose burning, tingling sensations persist long after tissues have healed. Molecular studies of spinal cord pathways demonstrate that neuronal and microglial changes in the spinal cord amplify pain signals even when no ongoing tissue damage exists. Your nerves fire spontaneously, creating electric-shock sensations or constant burning without any external trigger.
This distinction matters because neuropathic pain requires a fundamentally different treatment approach. Standard pain relievers target inflammation at injury sites, but nerve pain stems from malfunctioning neural circuits in your spinal cord and brain. For patients dealing with both chronic and acute symptoms, understanding the difference is crucial. To learn more about the transition from acute to chronic back pain and when specialist care may be needed, visit this resource comparing chronic vs. acute back pain.
Understanding this difference helps explain why medications that worked for past injuries may provide little relief now.
How Nerve Damage Changes the Way Your Nervous System Processes Pain
Peripheral nerve injury triggers a cascade of changes throughout your nervous system. Damaged nerves develop abnormal ion channels that cause spontaneous electrical firing. Your dorsal root ganglia—clusters of nerve cells near your spine—become hyperexcitable, sending pain signals without any stimulus.
Detailed mechanistic studies show that peripheral nerve injury mechanisms create ectopic activity, where nerves fire randomly along their length rather than just at nerve endings. This explains why you might feel burning pain in your foot even though the nerve damage occurred higher up in your leg.
Your spinal cord also undergoes structural changes. Neurons that normally process light touch begin responding to pain signals instead. This rewiring means that sensations like clothing brushing against your skin can trigger intense discomfort. I observe this phenomenon regularly when examining patients who report that even gentle pressure causes sharp pain.
Why Standard Pain Medications Often Fall Short for Nerve Pain
Anti-inflammatory drugs like ibuprofen work by blocking prostaglandins that cause tissue inflammation. Opioids bind to receptors that reduce pain signal transmission. Both approaches target pathways involved in injury-related pain but largely miss the mechanisms driving neuropathic pain.
Nerve pain involves microglial activation in your spinal cord. These immune cells release inflammatory molecules that sensitize pain pathways. Research on microglial activation shows that neuroinflammatory cascades create a self-perpetuating cycle of pain signaling that standard analgesics cannot interrupt effectively.
Your damaged nerves also develop abnormal sodium channels that generate spontaneous firing. Traditional pain medications do not address these ion channel changes. This explains why patients tell me their burning pain persists despite trying multiple over-the-counter and prescription medications.
Gabapentinoids, such as gabapentin and pregabalin, are used to treat neuropathic pain. Some antidepressants affect neurotransmitter levels in pain-processing pathways. However, medication responses vary significantly, and many patients require interventional approaches that directly modulate neural circuits. For a broader look at available chronic pain treatment options, explore these chronic pain treatment options at our practice.
The Role of Central Sensitization in Chronic Nerve Pain
Central sensitization occurs when your spinal cord and brain become hypersensitive to pain signals. Repeated nerve firing causes neurons in your spinal cord to lower their activation threshold. This means weaker signals can trigger pain responses, and normal sensations feel painful.
Your nervous system undergoes structural changes during central sensitization. Synaptic connections strengthen between pain-processing neurons. New connections form that weren't present before injury. Evidence indicates that central sensitization processes involve dorsal horn plasticity that amplifies incoming signals and prolongs pain perception.
I see central sensitization manifest as allodynia—pain from normally non-painful stimuli—and hyperalgesia—exaggerated pain responses to mildly painful stimuli. Patients describe how light touch or temperature changes trigger intense discomfort. These symptoms reflect fundamental changes in how your nervous system processes sensory information.
Central sensitization can persist even after peripheral nerve damage heals. Your nervous system maintains its hypersensitive state, creating chronic pain that outlasts the original injury. This mechanism explains why some patients experience years of burning pain despite normal imaging studies showing no ongoing tissue damage.
How Interventional Approaches Target Neuropathic Pain in Napa
Neuromodulation therapies deliver electrical signals that modulate overactive neural circuits directly. Spinal cord stimulation places electrodes near your spinal cord to interrupt pain signal transmission. Research shows that neuromodulation modulates dorsal root ganglia and spinal cord circuits, reducing spontaneous nerve firing and normalizing pain processing.
I perform spinal cord stimulation for patients whose neuropathic pain has not responded to conservative treatments. The therapy works by activating inhibitory pathways that reduce pain signal transmission to your brain. Different stimulation frequencies target specific neural mechanisms—high-frequency stimulation may work through different pathways than traditional low-frequency approaches.
Clinical trials demonstrate that 10-kHz spinal cord stimulation produces substantial pain relief in diabetic neuropathy by targeting spinal pathways that process nerve pain. Patients in these studies reported meaningful improvements in pain intensity and quality of life compared to medication management alone.
Dorsal root ganglion stimulation offers another option for localized nerve pain. This approach targets the nerve cell clusters where abnormal firing often originates. By modulating activity at this level, we can address pain in specific body regions without affecting broader areas.
Radiofrequency ablation may help when nerve pain stems from identifiable nerve branches. This procedure uses heat to interrupt pain signal transmission along specific nerves. I evaluate each patient's pain pattern, imaging findings, and response to diagnostic blocks to determine whether this targeted approach might provide relief.
When neuropathic pain is localized to the back, especially with features suggesting nerve involvement, learning about minimally invasive back pain procedures can be helpful for patients considering intervention.
The key to successful interventional treatment lies in accurate diagnosis. I perform detailed examinations and diagnostic procedures to identify which neural pathways are driving your pain. This precision allows me to match the intervention to your specific pain mechanisms, maximizing the likelihood of meaningful improvement.
One Patient's Experience
I've treated hundreds of patients whose burning, tingling pain never responded to standard medications, so I understand how isolating that journey can feel. When someone finally finds a physician who takes time to understand their specific pain mechanisms and offers targeted solutions beyond prescriptions, it often marks a turning point.
"I'm so glad that I finally found a doctor to treat my pain. Dr Weisbein and her staff took the time to understand my pain and offer treatment that didn't involve prescription medication. After only two visits I finally feel there may be light at the end of the tunnel."

Frequently Asked Questions
Why does my nerve pain feel like burning or electric shocks?
Damaged nerves develop abnormal ion channels that cause spontaneous electrical firing along their length. Your dorsal root ganglia become hyperexcitable, sending pain signals without any external trigger. This ectopic activity creates the burning, tingling, or electric-shock sensations you experience. Unlike injury-related pain that fades as tissues heal, these abnormal nerve signals persist because the nervous system itself has become hypersensitive. Central sensitization amplifies these signals in your spinal cord, making even light touch feel painful. This mechanism explains why your pain continues despite normal imaging studies showing no ongoing tissue damage.
Can nerve pain be treated without surgery or long-term medications?
Neuromodulation therapies offer interventional options that target neural circuits directly without requiring open surgery or daily medications. Spinal cord stimulation places small electrodes near your spinal cord to modulate overactive pain pathways. The procedure uses minimally invasive techniques, and the device can be adjusted to match your specific pain patterns. Many patients experience meaningful pain relief that allows them to reduce or eliminate medications that provided limited benefit. Dorsal root ganglion stimulation offers another targeted approach for localized nerve pain. I evaluate each patient's pain mechanisms through detailed examination and diagnostic procedures to determine which interventional option might restore function and improve quality of life.
How long does it take to see improvement with interventional treatments?
Most patients notice changes within days to weeks after starting neuromodulation therapy. Spinal cord stimulation typically begins with a trial period where we test the therapy before permanent implantation. During this trial, you'll experience how the stimulation affects your pain patterns and daily function. Some patients report immediate relief, while others notice gradual improvement as their nervous system adapts to the modulation. The timeline varies based on how long you've experienced neuropathic pain and the extent of central sensitization. I work closely with each patient to optimize device settings and ensure the therapy targets the specific neural pathways driving their symptoms, maximizing the likelihood of sustained improvement.
