Laser Therapy for Neuropathy: Is It Safe?

Laser Therapy for Neuropathy: Is It Safe?

Jul 24 2025

Peripheral neuropathy can be a frustrating and often painful condition that affects the nerves in the hands, feet, and other extremities. For those seeking relief beyond medications and conventional treatments, laser therapy may become an increasingly attractive option. But is it safe — and is it effective? 

What Is Peripheral Neuropathy?

Peripheral neuropathy occurs when nerves outside the brain and spinal cord become damaged. A person’s peripheral nervous system is responsible for sending information from the brain, spinal cord, and autonomic nervous system. When this system is compromised, you can experience the following in your hands, feet, ankles, and other extremities: 

  • Numbness or tingling.
  • Burning or stabbing pain.
  • Muscle weakness.
  • Sensitivity to touch.
  • Balance and stability issues, falling frequently.
  • Swelling and discoloration.

This condition can be caused by genetics, traumatic injuries, metabolic abnormalities, infections, autoimmune diseases, certain medications, or exposure to certain toxins. Approximately 50% of people with diabetes will develop peripheral neuropathy. 

If left untreated, this condition can grow worse, significantly affecting a person’s daily life and ability to function normally. 

What Is Laser Therapy?

Laser therapy, also known as low-level laser therapy (LLLT) or cold laser therapy, uses focused light energy to penetrate the skin and interact with cells, reducing symptoms and relieving pain. This treatment is non-invasive and often used in physical therapy and pain management clinics. 

It works by:

  • Increasing ATP production, which helps damaged nerve cells repair and function more efficiently.
  • Reducing oxidative stress and inflammation which reduces nerve pain and dysfunction.
  • Stimulating blood flow, which improves oxygen and nutrient delivery to affect nerves.

For peripheral neuropathy, laser therapy aims to:

  • Improve blood flow to damaged nerves.
  • Reduce inflammation.
  • Promote nerve regeneration.
  • Decrease pain signals.
  • Stimulate cellular activity. 

Is It Safe?

Laser therapy is considered safe when performed by a trained professional. Here are a few key safety considerations:

Non-Invasive — Laser therapy doesn’t involve needles or incisions. 

Minimal Side Effects — Most people experience no discomfort during or after treatment, although they may experience some temporary redness, warmth, or swelling. You may feel a soothing warmth or tingling during treatment. 

No Downtime — Patients can typically resume normal activities immediately after a session. 

FDA-Cleared — Many cold laser devices used in clinics are FDA-approved for pain relief and tissue healing. 

Who Should Avoid It?

While laser therapy is safe for most people, it may not be suitable for:

  • Individuals with active cancer (especially in the treatment area).
  • Pregnant women (unless cleared by a physician).
  • People with certain photosensitive conditions or those taking photosensitizing medications. 
  • Individuals with pacemakers or other implanted devices (depending on laser type).

Always consult your healthcare provider before beginning any new treatment.

What to Expect During Treatment

During Treatment:

  • You will typically sit or lie down comfortably.
  • Your provider will mark the area to be treated.
  • The laser device will be passed over the treatment area. 
  • You may feel a gentle warmth or slight tingling sensation. 
  • You may be provided with protective eyewear.

After Treatment: 

  • Expect some redness and mild swelling, which should subside quickly.
  • Your provider may recommend applying a cool compress or soothing gel. 
  • You will also receive specific instructions on how to care for the treated area, such as gentle cleansing and moisturizing. 
  • You may need to avoid the sun and use sunscreen after treatment.

Is It Effective?

Research on laser therapy for peripheral neuropathy is still ongoing, but some studies suggest that it can: 

  • Improve nerve function.
  • Reduce neuropathic pain.
  • Enhance quality of life.
  • Improve sleep quality, balance, mobility, and daily comfort.

While it can’t cure you of this condition, it can be a safe and important part of a treatment plan that includes nutrition, exercise, and other therapies. You should also note that all bodies function differently, and the number of treatments and success rate will vary. 

Some people experience relief quickly, while others may not notice improvement after the first or second session. However, after a series of treatments and as your body heals and nerve function is restored, you could experience significant relief from pain. 

Laser Therapy: Safe Relief for Peripheral Neuropathy 

Laser therapy is a safe, non-invasive, and drug-free option for managing the symptoms of peripheral neuropathy. While it’s not a cure, many patients experience reduced pain, improved nerve function, and a better quality of life after completing treatment. With minimal side effects and no downtime, it offers a promising alternative — or complement — to traditional approaches. As always, consult with a qualified healthcare provider to ensure laser therapy is the right choice for your specific condition and health needs.
