All You Need To Know About Nerve Pain
Medically Reviewed By:
Nerve pain or neuropathic pain occurs when nerves are damaged or malfunctioning, leading to sharp, shooting, or burning sensations. Unlike muscle or joint pain, which originates from physical structures, nerve pain stems from the nervous system.
This type of pain can be persistent and debilitating, affecting daily activities such as walking, sleeping, or even light touch. Common causes include diabetes, injuries, infections, and certain medical treatments.
This guide outlines the causes, symptoms, diagnostic methods, and treatment options for nerve pain.
How Chronic Nerve Pain Alters Sensory Neurons And Pain Signals
Pain is the body’s warning signal. While some pain subsides naturally, chronic nerve pain persists and may worsen without treatment. A recent study suggests that neurons responsible for sensing light touch may change function and begin signaling pain in cases of chronic nerve pain.
Since pain is a symptom, treatment requires identifying the root cause. However, in modern medical practice, treatments often focus on pain management rather than the underlying issue. A broader understanding of chronic pain can improve treatment strategies.
The Impact Of Chronic Pain
Chronic pain significantly affects daily life and well-being. Unlike acute pain, which resolves as injuries heal, chronic pain persists for weeks, months, or even years.
- Chronic pain is a widespread issue: Over 50 million adults (20.5%) in the U.S. experience chronic pain annually. Treatments like nonsteroidal anti-inflammatory drugs (NSAIDs) or opioids often provide only temporary relief, and opioids may even worsen pain over time.
Research indicates that while NSAIDs and opioids may provide short-term pain management, they do not always alleviate chronic pain. In some cases, opioids may even worsen chronic pain over time. - Chronic pain is a measurable condition: While the biopsychosocial pain theory has resurfaced, it is now clear that chronic pain causes quantifiable changes in the brain, visible through high-resolution functional MRIs.
- Chronic pain can be debilitating: Many strive to improve their quality of life despite chronic pain. For example, Joe, a father with severe knee pain, overcame severe knee pain without surgery, and Michelle, a dedicated athlete, managed her pain post-meniscus surgery to complete an IRONMAN race.
- Chronic pain is a serious health risk: Patients with chronic pain from conditions like arthritis are 50% more likely to attempt self harm, highlighting the severe mental health impact of persistent pain.
- Chronic pain after surgery is common: Up to half of knee replacement patients experience chronic pain post-surgery, with similar reports from hip replacement patients. In some cases, persistent pain following joint replacement may stem from nerve issues originating in the lower back.
Additionally, research has revealed that meniscus surgery may not provide better pain relief than placebo procedures. Spinal fusions for back pain have also been found to place strain on adjacent segments of the spine, potentially leading to increased back pain.
Chronic Nerve Pain Leads To Heightened Touch Sensitivity
Sensory neurons normally signal pain, but a recent study revealed that neurons responsible for pleasant touch can also start transmitting pain signals in chronic nerve pain cases. This happens due to a decrease in a specific RNA molecule (microRNA), making neurons hypersensitive to touch.
This heightened sensitivity, along with the impact on other nerve functions, can lead to various symptoms that affect everyday activities and overall well-being. Common effects of chronic nerve pain include:
- Numbness: Impaired nerve function may cause loss of sensation
- Balance issues and falls: Nerve damage can disrupt coordination
- Grip difficulties: Reduced sensation can make handling objects challenging
- Muscle weakness: Limited nerve communication weakens muscles
- Excessive sweating: Chronic nerve pain can disrupt autonomic nervous system functions
Key Factors Contributing To Neuropathic Pain
Neuropathic pain results from nerve dysfunction rather than injury or inflammation. Common causes include:
Injuries
Physical trauma, such as accidents, falls, or surgeries, can damage nerves, leading to neuropathic pain. During an injury, nerve compression, severing, or overstretching can disrupt nerve signals, resulting in persistent pain and heightened sensitivity in the affected area. This type of pain may continue long after the injury has healed.
Infection
Certain infections can cause significant nerve damage, leading to neuropathic pain. Viruses such as shingles (herpes zoster) and HIV are known to affect the nervous system, causing inflammation and nerve damage. Even after the infection is treated, the lingering effects on nerve fibers can result in long-term discomfort.
Vitamin B Deficiency
A deficiency in B vitamins, particularly B12, can lead to nerve damage and neuropathic pain. These vitamins are critical to maintaining healthy nerve function. Prolonged deficiency can cause nerve degeneration, resulting in tingling, numbness, and burning sensations that typically start in the feet and work their way up. Adequate intake of B vitamins is crucial for preventing and managing nerve discomfort linked to this deficiency.
Thyroid Problems
Thyroid disorders, such as hypothyroidism, can contribute to neuropathic pain by affecting nerve health. When thyroid hormone levels are imbalanced, the body’s metabolism slows, leading to fluid retention and swelling around nerves.
This compression of nerves can cause pain, tingling, or numbness, particularly in the hands and feet. Proper thyroid management is essential for preventing nerve discomfort related to this condition.
Diabetes
Diabetes is the leading cause of neuropathic pain, particularly diabetic neuropathy. Elevated blood sugar levels can lead to nerve damage over time, causing burning, tingling, or numbness, especially in the extremities.
Diabetic neuropathy is often progressive, impacting mobility and quality of life. Proper blood sugar management is critical for preventing or slowing the progression of nerve damage.
Medical Conditions
Several health conditions can affect the structure or function of the nervous system, contributing to neuropathic pain. These conditions often lead to nerve damage or dysfunction, resulting in chronic pain and sensory issues. Common medical conditions associated with nerve discomfort are the following:
- Atypical Trigeminal Neuralgia: A chronic condition characterized by persistent, aching, or burning facial pain due to nerve dysfunction. Symptoms may be unpredictable and vary in intensity, often affecting daily activities and quality of life. Read More About Atypical Trigeminal Neuralgia.
- Carpal Tunnel Syndrome: Carpal tunnel syndrome is caused by compression of the median nerve in the wrist, leading to numbness, tingling, weakness, or pain in the hand and fingers. Symptoms may worsen over time, affecting grip strength and fine motor skills. Read More About Carpal Tunnel Syndrome.
- Bulging Disc: A bulging disc occurs when a spinal disc extends beyond its normal space without rupturing. Depending on the affected area, it may cause localized pain or nerve compression, leading to numbness, tingling, or weakness in the back, neck, or limbs. Read More About Bulging Discs.
- Torn Discs: A torn disc, or annular tear, occurs when the outer layer of a spinal disc is damaged, potentially causing pain, inflammation, or nerve irritation. Symptoms may include localized back pain or radiating discomfort if the tear affects nearby nerves. Read More About Torn Discs.
When To Seek Medical Attention
While occasional nerve pain can be manageable, certain symptoms may indicate more serious nerve damage or an underlying condition requiring medical attention. You should consult a healthcare provider if you experience any of the following:
- Persistent pain lasting for several weeks or that worsens over time.
- Numbness or tingling that spreads or does not resolve.
- Difficulty with movement, balance, or coordination.
- Muscle weakness impacting daily activities.
- Sudden, severe pain following an injury or illness.
- Pain accompanied by unexplained fever, weight loss, or changes in bladder or bowel control.
Diagnosing Nerve Discomfort
Diagnosing nerve discomfort requires a thorough evaluation to determine the underlying cause and extent of nerve damage. Physicians use a combination of medical history, physical exams, and diagnostic tests to assess nerve function and identify the source of the discomfort.
Common diagnostic methods include:
- Physical and neurological exam: Physicians assess muscle strength, reflexes, and sensitivity to touch, as well as coordination and balance, to detect nerve function impairment.
- Electromyography (EMG): This test measures electrical activity in muscles, identifying abnormal nerve function and helping to detect nerve damage or compression.
- Nerve conduction studies: These tests evaluate how well electrical signals travel through nerves, providing insight into potential blockages or degeneration.
- Imaging tests: MRI or CT scans can visualize nerve structures, helping identify physical damage, such as herniated discs or tumors, that may be causing discomfort.
- Blood tests: Laboratory tests can reveal underlying conditions, like vitamin deficiencies, diabetes, or autoimmune disorders, that could contribute to nerve pain.
Conventional Treatment Options
Managing neuropathic pain requires a combination of approaches tailored to individual needs. Standard treatment options for addressing nerve pain:
- Medications: Anticonvulsants, antidepressants, and pain relievers are commonly prescribed to manage neuropathic pain by altering nerve signals or reducing inflammation. Physicians may also recommend topical treatments like lidocaine patches or capsaicin creams for localized relief.
- Nerve blocks: Nerve blocks involve injecting anesthetic medications near the affected nerves to temporarily interrupt pain signals, providing significant relief, especially for severe or persistent pain when other treatments prove ineffective.
- Physical therapy: Physical therapy helps improve mobility, strengthen muscles, and enhance coordination. A physical therapist can design a personalized exercise plan to help patients regain strength and function while addressing balance issues related to nerve damage.
- Alternative therapies: Alternative therapies are increasingly popular for managing nerve pain. These treatments stimulate the body’s natural healing processes, reduce inflammation, and promote relaxation to help alleviate discomfort:
- Massage: Massage can reduce muscle tension and improve circulation, offering relief from nerve pain. Regular sessions may also lower stress levels and support relaxation, which can benefit those with chronic pain.
- Acupuncture: Acupuncture involves inserting thin needles at specific points on the body to stimulate nerves and reduce pain. This method may help manage neuropathic pain by promoting the release of natural pain-relieving chemicals and enhancing nerve function.
