Nerve pain, also known as neuropathy, is a common condition affecting many Australians. It can be caused by diabetes, injuries, autoimmune disorders, or certain medications, leading to numbness, tingling, burning sensations, and muscle weakness. Managing neuropathy can be challenging, as there is no single cure—treatment typically focuses on pain relief and supporting nerve health.
Emerging research suggests that red light therapy may support nerve regeneration and help reduce discomfort associated with neuropathy. A study published in J Orthop Sci (2010) found that near-infrared light therapy (660 nm) promoted nerve regeneration and helped maintain antioxidation levels in damaged nerve tissue. This suggests that red light therapy may play a role in supporting nerve repair and reducing oxidative stress—two key factors in managing nerve pain.
This article explores what neuropathy is, its causes and symptoms, and how red light therapy may assist in managing this condition.
Understanding Nerve Pain/Neuropathy
Neuropathy occurs when the peripheral nerves—the nerves outside the brain and spinal cord—become damaged. These nerves control sensation, movement, and involuntary bodily functions like digestion and circulation.
When these nerves become impaired, they can lead to various symptoms, but most commonly, these are seen:
- Tingling or numbness, especially in the hands and feet
- Burning or sharp pain
- Muscle weakness or difficulty with coordination
- Sensitivity to touch or temperature changes
- Changes in blood pressure or digestion (if autonomic nerves are involved)
The severity of symptoms varies depending on which nerves are affected and how much damage has occurred.
What Causes Neuropathy?
Neuropathy occurs when the nerves outside the brain and spinal cord (peripheral nerves) become damaged or dysfunctional. This can happen due to a variety of reasons, ranging from chronic health conditions to external injuries or exposure to harmful substances. In some cases, the exact cause is unknown, which is referred to as idiopathic neuropathy.
When nerves are damaged, they struggle to transmit signals effectively, leading to symptoms like pain, tingling, numbness, muscle weakness, and temperature sensitivity. The severity of neuropathy can vary significantly depending on the underlying cause and how much nerve damage has occurred.
The most common causes of neuropathy in Australia
Diabetes (Diabetic Neuropathy)
One of the leading causes of neuropathy is diabetes, particularly in those with long-term, uncontrolled high blood sugar levels. It’s estimated that around 50% of people with diabetes develop some form of nerve damage.
High blood sugar levels damage the small blood vessels that supply oxygen and nutrients to the nerves, leading to nerve dysfunction, pain, and loss of sensation—particularly in the feet and hands. This condition, known as diabetic neuropathy, can make individuals more prone to injuries and infections, sometimes leading to severe complications like foot ulcers or amputation.
Managing blood sugar levels, maintaining a healthy diet, and using treatments like red light therapy to support circulation can help slow nerve damage progression.
Injuries and Nerve Compression
Physical trauma is another common cause of neuropathy. Nerves can be damaged due to:
Accidents – Falls, fractures, or direct injuries can sever or crush nerves, leading to pain, numbness, or even paralysis in the affected area.
Repetitive Strain – Repeated movements (e.g., typing, factory work, or prolonged tool use) can compress nerves, leading to conditions like carpal tunnel syndrome or sciatica.
Spinal Issues – Herniated discs, bone spurs, or spinal misalignment can pinch nerves, causing radiating pain or weakness.
Nerve compression can reduce blood flow to the nerves, preventing them from functioning properly. In many cases, targeted red light therapy may help by improving circulation and reducing inflammation around the affected nerves.
Autoimmune Disorders
Certain autoimmune conditions can attack the body’s own nerve tissue, causing chronic inflammation and nerve damage. Common autoimmune-related neuropathies include:
Rheumatoid Arthritis (RA) – Inflammatory damage to joints can also affect nearby nerves, leading to pain, tingling, or weakness.
Lupus – This condition can cause vasculitis (blood vessel inflammation), cutting off the nerve supply.
Multiple Sclerosis (MS) – While primarily affecting the central nervous system, MS can also damage peripheral nerves, impacting movement and sensation.
Since autoimmune disorders are often progressive, treatments aim to reduce inflammation and support nerve function. Red light therapy may help mitigate inflammatory responses and support nerve repair in these cases.
Chemotherapy and Medications (Chemotherapy-Induced Neuropathy – CIPN)
Certain medications—especially chemotherapy drugs used to treat cancer—can have neurotoxic effects, leading to nerve pain, numbness, or tingling in the hands and feet.
CIPN is particularly common in those undergoing prolonged chemotherapy treatments, as some drugs can damage the protective myelin sheath surrounding nerves. Other medications that may cause neuropathy include:
Some antibiotics (if used for long periods)
Certain epilepsy medications
Drugs used to treat high blood pressure
Research, including the J Orthop Sci (2010) study, suggests that red and near-infrared light therapy may support nerve regeneration by improving mitochondrial function. This has led to growing interest in red light therapy as a complementary approach for managing chemotherapy-induced neuropathy.
Vitamin Deficiencies and Excessive Alcohol Consumption
Nerve health depends on adequate levels of essential vitamins and minerals, particularly:
B vitamins (B1, B6, B12) – Crucial for nerve repair and function
Vitamin E – Acts as an antioxidant, helping protect nerves from damage
Copper – Supports nerve signal transmission
A lack of these nutrients, whether due to poor diet, digestive disorders, or excessive alcohol consumption, can contribute to nerve dysfunction and degeneration.
Chronic alcohol misuse can also lead to alcoholic neuropathy, where nerve cells are directly damaged due to prolonged exposure to toxic substances. Reducing alcohol intake and ensuring proper nutrition, along with supportive therapies like red light therapy, may help manage symptoms.
Managing Nerve Pain/Neuropathy Holistically
By addressing the underlying cause of neuropathy, individuals can take targeted steps to manage symptoms and slow disease progression. Whether through lifestyle changes, medical interventions, or alternative therapies like red light therapy, there are options available to help improve nerve health and overall well-being.
How Red Light Therapy May Help with Neuropathy
Supporting Nerve Regeneration
The J Orthop Sci study found that red and near-infrared light therapy improved nerve regeneration in damaged nerve tissue. Researchers suggest this may be due to enhanced mitochondrial function, which helps nerve cells produce the energy needed for repair.
When applied consistently, red light therapy for nerve regeneration may support the body’s natural healing process, particularly for diabetic neuropathy and nerve compression injuries.
