Quick Answer
Peripheral neuropathy means the nerves outside the brain and spinal cord are not working properly. Treatment depends on which nerves are affected and why, established through examination and AANEM-accredited nerve conduction and EMG testing performed in CNS offices across Las Vegas and Henderson.
Key Takeaways
- Neuropathy is a finding rather than a diagnosis. The useful question is which nerves are affected, in what pattern, and what is causing it, because those three answers determine whether anything can be reversed.
- Electrodiagnostic testing localises the problem. It distinguishes a nerve from a nerve root from the muscle, and separates acute change from long-standing change, which examination alone cannot reliably do.
- A significant proportion of neuropathies have an identifiable and modifiable cause. Diabetes and prediabetes, vitamin B12 deficiency, thyroid disease, alcohol, certain medications and some autoimmune conditions all appear, and each changes the plan.
- Small-fibre and large-fibre neuropathy behave differently and are tested differently. Standard nerve conduction studies assess large fibres, so a normal study does not exclude a small-fibre process causing burning pain.
- Treatment addresses two separate things: the cause, where one is found and modifiable, and the symptoms, particularly neuropathic pain. Confusing the two is why patients on pain medication alone often feel the condition is unaddressed.
01 — OverviewWhy neuropathy is a finding rather than a diagnosis
Patients are frequently told they have neuropathy and sent away with a prescription for the pain, which addresses the symptom and leaves the more useful questions unasked. Neuropathy describes that peripheral nerves are not working properly. It does not say which nerves, in what pattern, or why, and those three answers are what determine whether anything about the situation can be changed. This page sits within the wider neurological conditions library at Clinical Neurology Specialists.
Why it usually starts in the feet
The commonest pattern is symmetrical and begins distally, in the toes and feet, spreading upward over time and later involving the hands. The reason is length: the nerves running to the feet are the longest in the body, so a process affecting nerves generally shows there first. That pattern is itself diagnostic information, and a presentation that does not follow it, such as numbness confined to one limb or one nerve territory, points somewhere quite different and warrants a different investigation.
The three axes that matter
Which fibres are affected, whether the problem is in the nerve fibre itself or its insulating sheath, and whether it is progressing. Sensory fibres carry numbness, tingling and burning. Motor fibres carry weakness and wasting. Autonomic fibres carry blood pressure, sweating and digestive symptoms that patients rarely connect to a nerve problem at all. A neuropathy affecting one of these differs from one affecting all three, and the distinction shapes both investigation and prognosis.
Why the pattern matters more than the sensation
Patients describe neuropathy in vivid and varied language, and the description matters less than where the symptoms are. Burning, electric, crawling, walking-on-gravel and numb-but-painful are all common and none of them distinguishes one cause from another. Distribution does. Symmetrical and distal points toward a systemic process. One nerve territory points toward compression. Patchy and asymmetrical points toward something inflammatory or vascular. That is the reasoning an examination is built to apply.
Peripheral neuropathy is damage to or dysfunction of the nerves outside the brain and spinal cord, producing numbness, tingling, burning pain or weakness, most often beginning in the feet because the longest nerves are affected first.
02What electrodiagnostic testing establishes
Nerve conduction studies and electromyography are the instruments that turn a clinical impression into a localised finding, and they are the reason accreditation matters more here than almost anywhere else in neurology.
What each part measures
Nerve conduction studies measure how fast and how strongly a nerve carries a signal, using brief electrical pulses delivered through the skin. Electromyography uses a very fine needle electrode placed in specific muscles to assess how those muscles respond and whether they show changes of denervation or reinnervation. Together they distinguish a problem in the nerve from one in the nerve root or the muscle, separate damage to the fibre from damage to its insulating sheath, and indicate whether change is recent or long-standing. Detail is on the EMG and nerve conduction guide.
Why the accreditation is not a formality
Electrodiagnostic study quality varies considerably, and a poorly performed study can produce a finding that is not there or miss one that is. The American Association of Neuromuscular & Electrodiagnostic Medicine accreditation programme is a voluntary peer review of physician qualifications, equipment and study quality. CNS holds it at both offices and was the first physician-owned outpatient electrodiagnostic laboratory in Nevada to reach exemplary status. For a patient this means a study that is less likely to need repeating and a report that carries weight with whoever reads it next.
The limit worth knowing about
Standard nerve conduction studies assess large myelinated fibres. Small-fibre neuropathy, which characteristically produces burning pain and altered temperature sensation with relatively preserved strength and reflexes, can therefore coexist with an entirely normal study. That is not a failure of the test; it is the test measuring what it measures. A patient told their study was normal and their symptoms therefore unexplained has been given an incomplete account, and recognising the small-fibre pattern clinically is what fills the gap.
| Feature | Large-fibre | Small-fibre |
|---|---|---|
| Typical symptoms | Numbness, imbalance, tingling | Burning, altered temperature sensation |
| Reflexes | Often reduced | Often preserved |
| Strength | May be affected | Usually preserved |
| Nerve conduction study | Usually abnormal | Frequently normal |
| Balance | Commonly affected | Less commonly affected |
Told you have neuropathy and nothing more?
Which nerves, in what pattern, and why are the questions that change the plan.
03Causes worth looking for, because several are modifiable
The reason to investigate rather than simply medicate is that a meaningful proportion of neuropathies have an identifiable cause, and some of those causes respond to being addressed.
The commonest group
Diabetes and prediabetes account for a large share. Glucose handling short of a diabetes diagnosis can still produce neuropathy, which is why testing is worthwhile even without a known diagnosis.
Correctable directly
Vitamin B12 deficiency, and occasionally other deficiencies, produce neuropathy that can improve with replacement. Certain medications and bariatric surgery raise the risk.
Worth excluding
Thyroid disease, alcohol, some chemotherapy agents and other medications, kidney disease, and autoimmune or inflammatory neuropathies that respond to quite different treatment.
Why the investigation is targeted rather than exhaustive
A neuropathy work-up can be extended almost indefinitely, and beyond a certain point the additional tests rarely change management. The examination and the electrodiagnostic pattern narrow the field first, and laboratory work is then directed at what that pattern makes plausible. A patient handed a very long list of tests without that narrowing has usually been given breadth in place of reasoning.
When no cause is found
In a proportion of cases no cause is identified despite appropriate investigation, and that answer is reported honestly rather than dressed up. It changes the emphasis toward symptom management and monitoring, and it does not mean the investigation was wasted, because excluding treatable causes was the point. Where a pattern suggests an inflammatory neuropathy, which can respond to specific treatment, that possibility is pursued deliberately rather than left to chance. The Muscular Dystrophy Association publishes patient material on the wider group of neuromuscular disorders.
04Treatment: the cause and the symptoms are separate targets
Two different objectives get confused, and the confusion is why patients on pain medication alone often feel their condition has not been addressed. Treating the cause may slow or halt progression. Treating the symptoms makes the present tolerable. They are not substitutes for one another.
Addressing the cause where there is one
Glucose control where the cause is metabolic. Replacement where a deficiency is found. Reviewing and where possible changing a medication that is contributing. Reducing or stopping alcohol. Treating thyroid disease. Immune-directed treatment where an inflammatory neuropathy is identified, which is a different pathway entirely and one of the strongest arguments for establishing the diagnosis properly rather than accepting neuropathy as an endpoint.
Neuropathic pain, treated as its own problem
Neuropathic pain does not respond well to ordinary analgesics, and that is a feature of the mechanism rather than a matter of insufficient dose. The medications used for it are drawn from classes originally developed for other purposes, which frequently confuses patients who look them up, so it is worth explaining at the point of prescribing rather than leaving to be discovered. Response varies considerably between individuals, adjustment is normal, and finding a workable option often takes more than one attempt.
What realistic improvement looks like
Expectations are worth setting explicitly, because neuropathy is a condition where the honest answer differs from the hoped-for one. Where a modifiable cause is found and addressed, progression often slows and symptoms sometimes improve, though nerve recovery is slow and measured in months rather than weeks. Where no modifiable cause is found, the realistic aim is stability and tolerable symptoms rather than reversal. Neither of those is a reason to skip the investigation, because the difference between them is exactly what the investigation establishes, and a patient who knows which situation they are in makes better decisions than one who does not.
Balance, feet and the risks that get overlooked
Reduced sensation in the feet carries two consequences beyond discomfort. Balance depends on sensory feedback, so falls risk rises, and that is worth addressing directly through assessment and where appropriate physiotherapy. And an insensate foot is vulnerable to injury that goes unnoticed, which is why foot inspection and appropriate footwear are genuinely medical advice in this context rather than general wellbeing suggestions, particularly where diabetes is involved.
What CNS does not do
The practice is medical and diagnostic. It does not perform nerve surgery or run an interventional pain programme, and where a compressive lesion needs surgical decompression or a pain question needs an interventional approach, the referral is made with the accredited report attached. Nothing on this page promises an outcome; responses to both cause-directed and symptom-directed treatment vary between individuals. Options the practice does deliver are set out on the treatments hub.
05Neuropathy and the conditions it is confused with
Several conditions produce overlapping symptoms and need distinguishing, because treatment differs sharply between them.
Compression at a single site
Carpal tunnel syndrome affects the median nerve at the wrist and produces symptoms confined to that nerve territory rather than a symmetrical stocking distribution. It is a compression problem with its own pathway, described on the carpal tunnel page, and the same electrodiagnostic study that characterises a generalised neuropathy also localises this.
Nerve root rather than nerve
Radiculopathy arises where a nerve root is affected near the spine, producing symptoms in that root's distribution, often with back or neck pain. It can coexist with a generalised neuropathy, which makes the picture harder to read and makes electrodiagnostic localisation more valuable rather than less. Detail is on the radiculopathy and sciatica page.
Muscle and neuromuscular junction
Weakness without sensory symptoms points away from neuropathy and toward the muscle itself or the junction between nerve and muscle, as in myasthenia gravis. The examination distinguishes these, and electromyography contributes specifically. That page is myasthenia gravis.
Central rather than peripheral
Numbness can also originate in the spinal cord or the brain, and the distribution and associated findings are what separate that from a peripheral cause. This is the distinction where an examination earns its place most clearly, because the investigations and the urgency differ substantially, and a symmetrical distal pattern is reassuring in a way an asymmetrical or level-defined one is not.
06Peripheral neuropathy treatment across Southern Nevada
Both CNS offices carry a full accredited electrodiagnostic laboratory, so evaluation and testing happen at whichever address is the shorter drive. Clark County has a thin supply of neurologists relative to its population, and neuromuscular subspecialty availability is thinner still, which is worth factoring in when a study is being arranged.
Peripheral neuropathy treatment Henderson NV and Green Valley
Patients seeking peripheral neuropathy treatment Henderson NV attend the West Horizon Ridge Parkway office, just off the 215 Beltway. Peripheral neuropathy treatment Green Valley Henderson residents almost always find that address closest, and it holds the same accreditation as the Las Vegas site.
Peripheral neuropathy treatment Summerlin and the west valley
Peripheral neuropathy treatment Summerlin patients are usually closest to West Flamingo Road, which the 215 and Summerlin Parkway feed toward. Consultations, nerve conduction studies and electromyography are all performed there.
Peripheral neuropathy treatment North Las Vegas and the northwest
Peripheral neuropathy treatment North Las Vegas patients travel to whichever of the two offices is the shorter drive, following the consolidation from a wider footprint into two fully equipped sites. We will not imply a third location exists.
Peripheral neuropathy treatment Southern Nevada: why one laboratory matters over time
Peripheral neuropathy treatment Southern Nevada patients often need a second study eventually, to establish whether a neuropathy is progressing and at what rate. A comparison between two studies performed on the same equipment by the same laboratory under the same accreditation is interpretable; a comparison across two organisations introduces variables that weaken it. That argues for having both studies done in the same place, which is straightforward when both offices hold the accreditation independently. Two of the practice neurologists focus on neuromuscular medicine, and coverage is verified before your appointment, with detail on the insurance page.

Five board-certified physicians
Leo Germin, M.D., FAANEM, founder and medical director, triple board-certified in Neurology and Vascular Neurology through the ABPN and Neuromuscular Medicine through the ABEM, with subspecialty certification in Neurosonology and Neuroimaging. Anup Panduranga, M.D., fellowship-trained in epilepsy. Eric Gutglueck, M.D., neuromuscular medicine and neuromuscular ultrasound. Jessica A. Knirk, M.D., general adult neurology with Botox for chronic migraine. William Lujan, M.D., broad general adult neurology.
Four advanced practice providers
Fara Tan, APRN, MSCN, a Multiple Sclerosis Certified Nurse through the Multiple Sclerosis Nurses International Certification Board. Lindsey Evans, PA-C, general neurology and electromyography. Terra Fonseca, PA-C, a surgical and vascular background applied to general adult neurology. Alissa Nakamura, PA-C, board-certified through the NCCPA, with three years in pain management that transfer directly to nerve-injury and neuropathy questions.
Spread, not headcount
A referral that lands somewhere without neuromuscular or epilepsy depth often becomes a second referral, and each handoff adds weeks. Here an ambiguous nerve study can be reviewed by a neuromuscular specialist and an ambiguous EEG by a fellowship-trained epileptologist without the patient leaving the practice. Full biographies are on the providers page.
The Bottom Line
Ask which nerves, in what pattern, and why. Those three answers separate a neuropathy with a modifiable cause from one that needs symptom management, and only an examination with accredited electrodiagnostic testing behind it can give them.
Frequently Asked Questions
Is neuropathy a diagnosis?
Not on its own. It describes that peripheral nerves are not working properly. The useful questions are which nerves are affected, in what pattern, and why, because those three answers determine whether anything can be reversed rather than only managed.
What does nerve conduction testing show?
How fast and how strongly a nerve carries a signal, and alongside electromyography, whether the problem lies in the nerve, the nerve root or the muscle. It also separates recent change from long-standing change, which examination alone cannot reliably do.
My nerve study was normal but my feet burn. What now?
Standard nerve conduction studies assess large fibres. Small-fibre neuropathy characteristically produces burning pain and altered temperature sensation with preserved strength and reflexes, and can coexist with a completely normal study. Recognising that pattern clinically is what fills the gap.
Which causes of neuropathy can actually be treated?
Several. Diabetes and prediabetes through glucose control, vitamin B12 deficiency through replacement, thyroid disease, alcohol, and contributing medications where they can be changed. Inflammatory neuropathies respond to immune-directed treatment, which is a different pathway entirely.
Why does pain medication not seem to help?
Neuropathic pain does not respond well to ordinary analgesics, which is a feature of the mechanism rather than a question of dose. The medications used come from classes developed for other purposes, response varies between individuals, and finding a workable option often takes more than one attempt.
Does CNS perform surgery for nerve compression?
No. The practice is medical and diagnostic. Where a compressive lesion needs surgical decompression, the referral is made with the accredited report attached. CNS also does not run an interventional pain programme.
Why does accreditation matter for a nerve study?
Study quality varies, and a poorly performed study can produce a finding that is not there or miss one that is. Accreditation is a voluntary peer review of physician qualifications, equipment and study quality. CNS holds it at both offices and reached exemplary status.
Will I need the study repeated later?
Sometimes, to establish whether a neuropathy is progressing and at what rate. A comparison is most interpretable when both studies are performed by the same laboratory on the same equipment, which is straightforward here since both offices hold the accreditation independently.
How this page was sourced
Practice facts here come from Clinical Neurology Specialists directly: the electrodiagnostic accreditation held at both addresses, the exemplary-status designation, the two neurologists focused on neuromuscular medicine, and the absence of nerve surgery and interventional pain management from the scope. Clinical context is sourced to the organisations below.
The comparison table describes typical large-fibre and small-fibre patterns and is not a self-diagnosis tool, since the two frequently coexist. No prevalence figures or response rates appear, because they vary by cause and population. No outcome is promised. Scope is adults 18 and older, medical and diagnostic rather than surgical.
