As a medical professional, one of the most challenging conditions I see patients struggle with is chronic neuropathic pain. This complex disorder can significantly impact quality of life, causing not only physical discomfort but also emotional distress. In this in-depth guide, we’ll explore what chronic neuropathic pain is, its causes, symptoms, diagnosis, and treatment options. By the end, you’ll have a better understanding of this condition and how to manage it effectively.

What is Chronic Neuropathic Pain?

Chronic neuropathic pain is pain caused by damage or dysfunction in the nervous system that lasts for more than three months[1]. It can originate from the peripheral nervous system (nerves outside the brain and spinal cord) or the central nervous system (brain and spinal cord).

Unlike acute pain, which is a normal response to tissue injury, chronic neuropathic pain persists long after an injury has healed. The pain is often described as shooting, burning, or electric-shock like and may be accompanied by other sensations like tingling, numbness, or sensitivity to touch[2].

Causes of Chronic Neuropathic Pain

Neuropathic pain can result from a wide range of conditions that affect the nervous system. Some common causes include:

Diabetes (Diabetic Neuropathy)

Diabetic neuropathy is nerve damage caused by chronically high blood sugar levels. It most often affects the nerves in the feet and legs, causing symptoms like pain, numbness, and tingling. Up to 50% of people with diabetes may develop neuropathy[3].

Maintaining good blood sugar control through diet, exercise, and medication can help prevent or slow the progression of diabetic neuropathy. Regular foot exams are also important to identify any signs of nerve damage early on.

Shingles (Postherpetic Neuralgia)

Shingles is a viral infection caused by the reactivation of the varicella-zoster virus, which causes chickenpox. The infection can damage nerve fibers, leading to a chronic pain condition called postherpetic neuralgia (PHN).

PHN affects about 10-15% of people who develop shingles, most often in those over age 60[4]. The pain can be severe and may persist for months or even years after the shingles rash has healed. Early treatment with antiviral medications can reduce the risk of developing PHN.

Chemotherapy-Induced Peripheral Neuropathy

Certain chemotherapy drugs used to treat cancer can damage peripheral nerves, leading to pain, numbness, and tingling in the hands and feet. This is known as chemotherapy-induced peripheral neuropathy (CIPN).

CIPN affects up to 68% of patients receiving chemotherapy[5]. Symptoms may improve after treatment ends, but some people experience long-term effects. Adjusting chemotherapy doses or using neuroprotective agents may help prevent or minimize CIPN.

Other Causes

Chronic neuropathic pain can also result from:

  • Multiple sclerosis
  • Spinal cord injury
  • Stroke
  • Vitamin B12 deficiency
  • Alcoholism
  • Carpal tunnel syndrome
  • Trigeminal neuralgia

In some cases, the exact cause of neuropathic pain may be unknown (idiopathic).

Symptoms of Chronic Neuropathic Pain

The symptoms of chronic neuropathic pain can vary from person to person but may include:

  • Burning, shooting, or electric-shock like pain
  • Tingling or “pins and needles” sensations
  • Numbness or reduced sensation
  • Allodynia (pain from normally non-painful stimuli, like light touch)
  • Hyperalgesia (increased pain from normally painful stimuli)

These symptoms can be constant or may come and go. They can also range from mild to severe and may worsen over time.

In addition to pain, people with chronic neuropathic pain often experience:

  • Sleep disturbances
  • Fatigue
  • Mood changes (e.g. depression, anxiety, irritability)
  • Difficulty concentrating
  • Reduced quality of life

The emotional impact of chronic pain can be just as significant as the physical symptoms. It’s important to address both aspects when managing neuropathic pain.

Diagnosing Chronic Neuropathic Pain

Diagnosing chronic neuropathic pain involves a combination of:

Medical History

Your doctor will ask about your symptoms, when they started, and any underlying health conditions you may have. They’ll also want to know about any medications, supplements, or substances you use.

Be as specific as possible when describing your pain, including:

  • Location
  • Intensity (mild, moderate, severe)
  • Quality (e.g. burning, shooting, aching)
  • Aggravating or relieving factors
  • Impact on daily activities and sleep

Physical Examination

A thorough physical exam can help identify signs of nerve damage, such as:

  • Altered sensation (e.g. reduced or heightened sensitivity to touch, temperature, vibration)
  • Muscle weakness or atrophy
  • Reduced reflexes
  • Changes in skin, hair, or nails

Your doctor may also check your coordination, balance, and gait.

Diagnostic Tests

Various tests can help confirm a diagnosis of neuropathic pain and determine the underlying cause:

Quantitative sensory testingAssesses response to touch, temperature, and vibration
Nerve conduction studiesMeasure how quickly electrical signals travel through nerves
Electromyography (EMG)Evaluates electrical activity in muscles
Skin biopsyExamines nerve fiber density in the skin
Imaging tests (e.g. MRI, CT)Visualize structural damage to the nervous system
Blood testsCheck for underlying conditions like diabetes or vitamin deficiencies

Screening tools like the DN4 questionnaire and painDETECT can also help identify neuropathic pain based on specific symptoms[6].

Treating Chronic Neuropathic Pain

Managing chronic neuropathic pain often requires a multifaceted approach tailored to each individual. Treatment may involve a combination of:


Several types of medications can help alleviate neuropathic pain:

  • Antidepressants: Tricyclic antidepressants (e.g. amitriptyline, nortriptyline) and serotonin-norepinephrine reuptake inhibitors (SNRIs) like duloxetine and venlafaxine can help relieve pain by altering chemical messengers involved in pain signaling[7].
  • Anticonvulsants: Medications like gabapentin and pregabalin, originally developed to treat seizures, can also effectively reduce neuropathic pain by calming overactive nerves[8].
  • Topical treatments: Lidocaine or capsaicin patches and creams can provide localized pain relief with fewer side effects than oral medications[9].
  • Opioids: While effective for severe pain, opioids are generally reserved as a last resort due to risks of side effects, tolerance, and addiction[10].

The specific medication regimen depends on factors like symptom severity, underlying cause, other health conditions, and individual preferences. It may take some trial and error to find the most effective combination and doses.

Non-Pharmacologic Therapies

Medications are just one piece of the puzzle when it comes to managing chronic neuropathic pain. Non-drug therapies can be equally important, including:

Physical Therapy

Physical therapy can help improve strength, flexibility, and function in people with neuropathic pain. Techniques may include:

  • Stretching and range of motion exercises
  • Strengthening exercises
  • Gait and balance training
  • Manual therapy (e.g. massage, joint mobilization)
  • Heat or cold therapy
  • Transcutaneous electrical nerve stimulation (TENS)

A physical therapist can design a personalized exercise program based on your specific needs and goals.

Occupational Therapy

Occupational therapy focuses on helping you perform daily activities more easily and safely. An occupational therapist may recommend:

  • Adaptive equipment (e.g. braces, splints, assistive devices)
  • Ergonomic modifications at home or work
  • Energy conservation and pacing techniques
  • Stress management and relaxation strategies

The goal is to maximize your independence and participation in meaningful activities despite pain.

Psychological Counseling

Chronic pain can take a toll on mental health, leading to depression, anxiety, and reduced quality of life. Psychological interventions can help you cope with the emotional impact of pain and develop healthy ways of thinking and behaving.

Options may include:

  • Cognitive-behavioral therapy (CBT): Focuses on identifying and changing negative thought patterns and behaviors that worsen pain
  • Acceptance and commitment therapy (ACT): Emphasizes accepting pain and engaging in valued activities despite it
  • Biofeedback: Uses sensors to help you learn to control physiological responses to pain, like muscle tension and heart rate
  • Mindfulness and relaxation techniques: Practices like deep breathing, progressive muscle relaxation, and meditation can help reduce stress and promote a sense of calm

A mental health professional can work with you to develop a personalized plan based on your needs and preferences.

Complementary Therapies

Some people find relief from neuropathic pain with complementary and alternative medicine (CAM) therapies, such as:

  • Acupuncture: Involves inserting thin needles into specific points on the body to alleviate pain and promote healing
  • Massage therapy: Uses various techniques to manipulate soft tissues, reduce muscle tension, and improve circulation
  • Yoga and tai chi: Gentle movement practices that combine physical postures, breathing exercises, and meditation
  • Herbal and nutritional supplements: Some supplements like alpha-lipoic acid, acetyl-L-carnitine, and vitamin B12 may help reduce neuropathic pain, but more research is needed to confirm their effectiveness and safety[11]

Always talk to your doctor before trying any CAM therapies, as some may interact with medications or be unsafe for certain conditions.

Interventional Procedures

In some cases, more invasive procedures may be recommended to manage chronic neuropathic pain:

Nerve Blocks

Nerve blocks involve injecting a local anesthetic, sometimes with a corticosteroid, near a specific nerve or group of nerves to temporarily relieve pain. They can be used for diagnostic or therapeutic purposes.

Types of nerve blocks used for neuropathic pain include:

  • Sympathetic nerve blocks: Used for complex regional pain syndrome (CRPS) and other conditions involving the sympathetic nervous system
  • Peripheral nerve blocks: Target specific nerves in the face, arms, or legs
  • Neuraxial blocks: Involve injections into or around the spinal cord, such as epidurals or intrathecal pumps

Nerve blocks can provide short-term relief and may need to be repeated for ongoing pain management.

Spinal Cord Stimulation

Spinal cord stimulation (SCS) involves implanting a small device that sends electrical pulses to the spinal cord to interrupt pain signals. It’s typically reserved for severe neuropathic pain that hasn’t responded to other treatments.

SCS works by delivering mild electrical currents through leads placed in the epidural space near the spinal cord. The electrical pulses create a tingling sensation (paresthesia) that masks pain. Newer forms of SCS, like high-frequency and burst stimulation, can provide pain relief without paresthesia[12].

A trial period with a temporary external stimulator is usually done first to assess effectiveness before permanent implantation. SCS is generally considered safe but does carry risks of infection, lead migration, and device complications.

Intrathecal Pain Pump

An intrathecal pain pump is a surgically implanted device that delivers pain medication directly into the spinal fluid surrounding the spinal cord. This allows for lower doses of medication compared to oral administration, which can reduce side effects.

Intrathecal pumps are most often used for cancer-related pain or severe neuropathic pain that hasn’t responded to other treatments[13]. Medications commonly used include opioids, local anesthetics, clonidine, and ziconotide.

Like SCS, a trial period is usually done before permanent implantation to assess effectiveness and monitor for side effects. Regular pump refills and maintenance are required.

Living with Chronic Neuropathic Pain

In addition to medical treatments, there are several self-care strategies that can help you manage chronic neuropathic pain and improve your overall quality of life:

Pain Management Plan

Work with your healthcare team to develop a personalized pain management plan. This should include:

  • Realistic goals for pain relief and functional improvement
  • A combination of pharmacologic and non-pharmacologic therapies
  • Regular follow-up to assess progress and make adjustments as needed
  • A plan for flare-ups or breakthrough pain

Having a written plan can help you feel more in control and ensure everyone is on the same page.

Pacing and Energy Conservation

Pacing involves breaking up activities into smaller, more manageable parts and taking frequent breaks to avoid overdoing it. Energy conservation means finding ways to simplify tasks and conserve your energy for the things that matter most.

Some tips for pacing and energy conservation include:

  • Prioritize activities and focus on what’s most important to you
  • Break tasks into smaller steps and take breaks as needed
  • Use assistive devices or adaptive equipment to make activities easier
  • Delegate tasks to others when possible
  • Schedule rest periods throughout the day

Learning to listen to your body and respect your limits can help prevent pain flare-ups and fatigue.

Stress Management

Stress can worsen chronic pain and make it harder to cope. Finding healthy ways to manage stress is an important part of living with neuropathic pain.

Some effective stress management techniques include:

  • Deep breathing exercises
  • Progressive muscle relaxation
  • Meditation or mindfulness practices
  • Engaging in hobbies or activities you enjoy
  • Spending time with supportive friends and family
  • Journaling or expressive writing

Experiment with different techniques to find what works best for you. Consistency is key – try to incorporate stress management into your daily routine.

Healthy Lifestyle Habits

Adopting healthy lifestyle habits can help improve overall health and reduce the impact of chronic pain. This includes:

  • Eating a balanced diet rich in fruits, vegetables, whole grains, and lean proteins
  • Staying hydrated by drinking plenty of water throughout the day
  • Getting regular exercise as tolerated (e.g. walking, swimming, gentle stretching)
  • Maintaining a healthy weight
  • Getting enough quality sleep each night
  • Avoiding smoking and excessive alcohol use

Small changes can add up over time. Work with your healthcare team to develop a plan that’s realistic and sustainable for you.

Support System

Having a strong support system is crucial when living with chronic neuropathic pain. Surround yourself with people who understand and can offer practical and emotional support.

Consider joining a chronic pain support group, either in-person or online. Connecting with others who have similar experiences can provide validation, encouragement, and a sense of community.

Don’t be afraid to ask for help when you need it. Let friends and family know specific ways they can support you, whether it’s helping with errands, providing a listening ear, or simply understanding when you need to cancel plans.

When to Seek Help

While self-care strategies can be effective, there may be times when you need additional support. Reach out to your healthcare team if you experience:

  • Worsening pain or new symptoms
  • Side effects from medications
  • Difficulty coping emotionally
  • Thoughts of self-harm or suicide

Your doctor can adjust your treatment plan or refer you to specialists like pain management physicians, mental health professionals, or rehabilitation therapists as needed.

Remember, you don’t have to suffer in silence. Help is available.

The Bottom Line

Living with chronic neuropathic pain can be challenging, but with the right combination of treatments and self-care strategies, it is possible to manage symptoms and maintain a good quality of life.

Work closely with your healthcare team to develop an individualized treatment plan that addresses both the physical and emotional aspects of pain. Be open and honest about your symptoms, goals, and concerns.

Stay active and engaged in activities that bring you joy and a sense of purpose. Pace yourself and listen to your body, but don’t let pain control your life.

Surround yourself with a supportive network of family, friends, and healthcare professionals who can offer encouragement and practical assistance when needed.

Remember, managing chronic neuropathic pain is a journey. There may be ups and downs along the way, but with perseverance and the right tools, you can live a fulfilling life despite the challenges.
