Peripheral neuropathy, a condition resulting from damage to your peripheral nerves, can lead to pain, numbness, and weakness, significantly impacting your quality of life. Seeking the expertise of a Neuropathy Doctor is crucial for accurate diagnosis and effective management. This article delves into the diagnosis and treatment of peripheral neuropathy, providing comprehensive information to empower you on your journey to recovery and well-being.
Diagnosing Peripheral Neuropathy: What to Expect from a Neuropathy Doctor
Identifying the root cause of peripheral neuropathy is the first step towards effective treatment. A neuropathy doctor, often a neurologist or a physician specializing in nerve disorders, will employ a thorough diagnostic process. This typically involves:
-
Comprehensive Medical History Review: Your neuropathy doctor will start by gathering a detailed account of your medical history. This includes discussing your symptoms – when they started, what triggers them, and how they affect your daily life. They will also inquire about your lifestyle, including potential exposure to toxins, alcohol consumption, and any family history of neurological conditions.
-
Neurological Examination: A crucial part of the diagnosis is a neurological exam. During this exam, your neuropathy doctor will assess:
- Tendon Reflexes: Checking reflexes can indicate nerve damage.
- Muscle Strength and Tone: Evaluating muscle strength helps identify weakness caused by nerve issues.
- Sensory Function: Testing your ability to feel different sensations like touch, vibration, and temperature changes helps pinpoint nerve involvement.
- Balance and Coordination: Assessing these functions can reveal the impact of neuropathy on motor skills.

Advanced Tests for Neuropathy Diagnosis
In addition to the physical exam, your neuropathy doctor may recommend various tests to confirm the diagnosis and identify the underlying cause of your peripheral neuropathy:
-
Blood Tests: These are essential to screen for underlying conditions that can cause neuropathy. Blood tests can detect:
- Vitamin Deficiencies: Low levels of certain vitamins, like B12, can lead to nerve damage.
- Diabetes: Elevated blood sugar levels are a major cause of peripheral neuropathy.
- Inflammation: Markers of inflammation can indicate autoimmune or inflammatory conditions affecting the nerves.
- Metabolic Disorders: Metabolic imbalances can sometimes contribute to neuropathy.
-
Imaging Tests: If structural issues are suspected, imaging tests may be ordered.
- CT Scans and MRI Scans: These scans can help visualize your spinal cord and surrounding tissues to identify herniated disks, compressed nerves (pinched nerves), tumors, or other abnormalities affecting nerves, blood vessels, and bones.
-
Nerve Function Tests: These tests directly assess the health and function of your nerves.
- Electromyography (EMG): EMG measures the electrical activity of your muscles. A thin needle electrode is inserted into a muscle to record electrical activity during muscle contraction and rest. EMG helps detect nerve damage and muscle dysfunction.
- Nerve Conduction Study: Often performed alongside EMG, this study uses surface electrodes and a mild electrical current to stimulate nerves. Your neuropathy doctor will record how your nerves respond to this stimulation, revealing the speed and strength of nerve signals.

-
Autonomic Reflex Screen: This specialized nerve function test evaluates the function of autonomic nerve fibers, which control involuntary functions like heart rate, blood pressure, and sweating.
-
Sweat Test: Measures your body’s ability to sweat, assessing the function of small nerve fibers.
-
Sensory Tests: Quantify your ability to perceive different sensations like light touch, vibration, cooling, and heat, providing detailed information about sensory nerve function.
-
Nerve Biopsy: In some cases, a nerve biopsy may be necessary. This involves removing a small sample of a nerve, typically a sensory nerve, for microscopic examination to identify the cause of neuropathy.
-
Skin Biopsy: A skin biopsy is a less invasive procedure where a small skin sample is taken to analyze the density of nerve endings in the skin. This can be particularly useful in diagnosing small fiber neuropathy.
Treating Peripheral Neuropathy: Working with Your Neuropathy Doctor
Once diagnosed, the focus shifts to managing the underlying cause of your neuropathy and alleviating symptoms. Treatment strategies are tailored to the individual and often involve a combination of approaches guided by your neuropathy doctor.
Medications for Neuropathy Symptom Relief
While medications cannot cure peripheral neuropathy in most cases, they play a vital role in managing pain and other debilitating symptoms. Common medications prescribed by a neuropathy doctor include:
- Pain Relievers:
- Over-the-counter (OTC) Pain Relievers: Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen can be effective for mild neuropathy pain.
- Anti-seizure Medications:
- Gabapentin and Pregabalin: These medications, originally developed for epilepsy, have proven effective in managing nerve pain. They work by calming overactive nerves. Common side effects include drowsiness and dizziness.
- Topical Treatments:
- Lidocaine Cream and Patches: Topical lidocaine can provide localized pain relief. Creams are available OTC, while patches are prescription strength. Side effects may include drowsiness, dizziness, and skin numbness at the application site.
- Antidepressants:
- Tricyclic Antidepressants (e.g., Amitriptyline, Nortriptyline): These older antidepressants can modulate pain signals in the brain and spinal cord. Side effects can include dry mouth, drowsiness, and constipation.
- Serotonin and Norepinephrine Reuptake Inhibitors (SNRIs) (e.g., Duloxetine, Venlafaxine, Desvenlafaxine): SNRIs like duloxetine are specifically approved for diabetic neuropathy pain. Common side effects include nausea, drowsiness, and changes in appetite.
Therapies and Procedures for Neuropathy Management
Beyond medications, various therapies can significantly improve neuropathy symptoms and overall function. Your neuropathy doctor may recommend one or more of the following:
-
Scrambler Therapy: This non-invasive therapy uses electrical impulses applied to the skin to transmit non-pain signals to the brain. It aims to “scramble” pain signals and retrain the brain to perceive less pain.
-
Spinal Cord Stimulation (SCS): For chronic, intractable pain, SCS may be an option. This involves implanting a neurostimulator device that sends low-level electrical impulses to block pain signals from reaching the brain.
-
Plasma Exchange, Steroids, and Intravenous Immune Globulin (IVIG): These treatments are typically reserved for inflammatory or autoimmune-related neuropathies causing significant weakness, numbness, or balance problems. They are not primarily used for pain management alone.
-
Physical Therapy: Essential for patients experiencing muscle weakness or balance issues due to neuropathy. Physical therapy programs can help improve muscle strength, coordination, and balance, reducing the risk of falls and improving mobility. Adaptive devices like braces, canes, walkers, or wheelchairs may also be recommended.
-
Surgery: In cases where neuropathy is caused by nerve compression, such as from tumors or entrapment, surgery may be necessary to relieve pressure on the affected nerve.

Lifestyle Adjustments and Home Remedies for Neuropathy
In addition to medical treatments, lifestyle modifications and home remedies can play a supportive role in managing peripheral neuropathy symptoms:
-
Foot Care: Meticulous foot care is crucial, especially for individuals with diabetic neuropathy.
- Daily Foot Checks: Inspect your feet daily for blisters, cuts, and calluses.
- Appropriate Footwear: Wear soft, loose-fitting cotton socks and well-padded shoes.
- Bedding Adjustment: Use a semicircular hoop to keep bedcovers off sensitive feet if needed.
-
Regular Exercise: Moderate exercise, such as walking regularly, can reduce neuropathy pain, improve muscle strength, and help manage blood sugar levels, especially in diabetic neuropathy. Gentle exercises like yoga and tai chi can also be beneficial. Water-based exercises like swimming may be suitable for those with foot pain.
-
Smoking Cessation: Smoking impairs circulation, increasing the risk of foot problems and other neuropathy complications. Quitting smoking is highly recommended.
-
Healthy Diet: Nutritious meals rich in fruits, vegetables, whole grains, and lean protein provide essential vitamins and minerals crucial for nerve health.
-
Limit Alcohol Intake: Excessive alcohol consumption can worsen peripheral neuropathy. Moderation or abstinence is advised.
-
Blood Sugar Management: For individuals with diabetes, strict blood sugar control is paramount to manage diabetic neuropathy and prevent further nerve damage.
