Treatment of Trigeminal Neuralgia Using LLLT/PBMT

Low Level Laser Therapy (LLLT), also known as Photobiomodulation Therapy (PBMT), uses red and near-infrared light applied over targeted areas. In our clinic it is used as part of a GP-led treatment approach for selected presentations, including selected trigeminal nerve pain presentations after appropriate medical assessment.

PBMT/LLLT is non-invasive and generally well tolerated. Suitability and response vary, and treatment recommendations depend on the diagnosis, severity, duration of symptoms and individual clinical factors. PBMT/LLLT has been studied for a range of musculoskeletal pain and injury conditions, including some pain and nerve-related presentations. See our references page for supporting literature.

Key Points

  • Trigeminal neuralgia (TN) is a neurological pain condition characterised by intense, sharp, electric shock-like or stabbing pain along one or more branches of the trigeminal nerve.
  • Common causes include vascular compression of the trigeminal nerve, multiple sclerosis, tumours or other structural causes, facial trauma, post-herpetic nerve irritation or idiopathic nerve sensitivity.
  • TN requires careful medical assessment. MRI or specialist review may be required to exclude compression, tumour, multiple sclerosis or other neurological causes.
  • LLLT/PBMT is considered only for selected presentations where symptoms appear related to nerve irritation, local inflammatory sensitivity or post-traumatic or post-viral nerve pain.
  • LLLT/PBMT is unlikely to help when TN is caused by mechanical compression from a blood vessel, tumour or structural lesion. These situations require medical, neurological or surgical management.
  • LLLT/PBMT may also have limited benefit in TN associated with multiple sclerosis because the underlying process involves central nervous system demyelination.
  • Standard treatments for TN may include anticonvulsant medicines, pain management, nerve blocks or surgery. LLLT/PBMT is considered an adjunctive option, not a replacement for appropriate medical care.
  • Treatment is GP-led by Dr Shikha Parmar and delivered as part of a structured six-week program with individualised advice and review.

What is Trigeminal Neuralgia (TN)?

Trigeminal neuralgia (TN) is a neurological disorder that causes severe facial pain, usually on one side. The trigeminal nerve carries sensory information from the face to the brain. When this nerve is irritated, compressed or damaged, it can produce sudden and intense episodes of shooting, stabbing or electric shock-like pain.

Pain episodes may last seconds to minutes and can be triggered by everyday activities such as talking, chewing, brushing teeth, shaving, touching the face or exposure to wind. For some people, the fear of triggering pain can significantly affect eating, speaking, social activity and quality of life.

TN is most commonly associated with a blood vessel pressing on the trigeminal nerve, but it may also be related to ageing, trauma, shingles, multiple sclerosis, tumours or other neurological conditions. Because some causes require specialist treatment, assessment and appropriate investigation are important.

Causes of Trigeminal Neuralgia

  • Blood vessel compression: an artery or vein may press on the trigeminal nerve. This is a common cause of classic TN and may require specialist management.
  • Multiple sclerosis: MS can damage the protective myelin covering of nerve fibres and may cause TN-like pain.
  • Facial trauma or surgery: injury or surgery affecting the trigeminal nerve can lead to local nerve irritation or neuropathic pain.
  • Post-viral nerve irritation: shingles or other viral nerve irritation can sometimes affect trigeminal nerve branches.
  • Age-related change: nerve and vascular changes may increase vulnerability to compression or irritation.
  • Tumours or abnormal growths: these can compress or irritate the trigeminal nerve and require medical or surgical assessment.

Where LLLT May Help

LLLT/PBMT is considered for selected trigeminal nerve pain presentations where assessment suggests local nerve irritation, trauma-related nerve sensitivity or post-viral nerve irritation rather than active structural compression. Treatment is applied externally and aims to help modulate local pain and inflammatory processes without pressure, manipulation or mechanical loading of the sensitive nerve region.

LLLT/PBMT is unlikely to be the primary treatment where TN is caused by mechanical pressure on the nerve from a blood vessel, tumour or other structural lesion. In those cases, the pressure itself may need medical, neurological or surgical management. TN associated with multiple sclerosis may also respond differently because the underlying process involves demyelination within the nervous system.

Symptoms of Trigeminal Neuralgia

  • Sharp, stabbing, shooting or electric shock-like facial pain
  • Pain along the jaw, gums, teeth, cheek, eye or forehead depending on the nerve branch involved
  • Pain triggered by talking, chewing, brushing teeth, shaving, washing the face or light touch
  • Brief repetitive bursts of severe pain, sometimes occurring many times per day
  • Tenderness, discomfort or altered sensation between pain attacks in some patients
  • Avoidance of eating, speaking or facial contact because of fear of triggering pain

New facial weakness, numbness, balance problems, double vision, severe headache, progressive neurological symptoms or pain associated with a rash near the eye requires prompt medical assessment.

How is Trigeminal Neuralgia Diagnosed?

Diagnosis is based on careful clinical evaluation. Dr Shikha Parmar will take a detailed history of symptoms, pain location, triggers, duration, frequency, previous shingles or trauma, medication history and the impact on daily life.

Examination may assess the painful area and trigeminal nerve function. MRI may be recommended to look for vascular compression, multiple sclerosis, tumour or other structural causes. In some cases, dental causes, sinus disease or other facial pain conditions also need to be excluded.

Trigeminal Neuralgia – Treatment Overview

Low Level Laser Therapy (LLLT), also known as Photobiomodulation Therapy (PBMT), is considered as part of a GP-led management plan for selected trigeminal nerve pain presentations. Treatment is directed externally over relevant nerve pathways and surrounding tissues. It may help modulate local pain and inflammatory processes and support nerve and soft tissue recovery where irritation is present, without applying mechanical stress to the trigeminal nerve region.

 

Why Consider Low Level Laser Therapy (LLLT)?

Standard treatments for TN often include anticonvulsant medication, pain medication, nerve blocks and, in selected cases, surgery. These treatments may be essential, particularly where vascular compression or another structural cause is identified. Some patients continue to experience persistent nerve sensitivity, medication side effects or incomplete symptom relief. LLLT/PBMT can be considered as an adjunctive option where assessment suggests local nerve irritation or post-viral or trauma-related nerve sensitivity and where a gentle, non-invasive approach is appropriate.

How LLLT Works

LLLT uses red and near-infrared light and may support:

  • Helping modulate inflammation and oxidative stress
  • Local circulation and oxygen delivery
  • Lymphatic drainage
  • Cellular energy production (ATP)
  • Nerve and soft tissue recovery processes where irritation is present
  • Assisting pain reduction without loading, pressing or mechanically stressing the trigeminal nerve region

Non-Invasive and Supported by Research

PBMT/LLLT is non-invasive and generally well tolerated. It has been studied in a range of musculoskeletal pain and injury conditions. Individual responses vary, and outcomes depend on the condition being treated and the stage of recovery. Read more here.

See how LLLT may support the cellular environment involved in tissue recovery here.

Our Treatment Program

All patients are assessed by Dr Shikha Parmar (GP). Treatment is delivered within a structured six-week program, including:

  • Up to 12 LLLT sessions
  • Early progress review after the first 6 treatments
  • Individualised advice and activity modification
  • Guided rehabilitation to support longer-term function

Progress is reviewed during the program. Many patients notice appreciable improvement after the first 6 treatments. If there has not been sufficient improvement by this review point, further treatment may not be recommended.

Cost / FAQ

At Laser Pain Therapy, we use the terms Low-Level Laser Therapy (LLLT) and Photobiomodulation Therapy (PBMT) interchangeably, as they both refer to the same therapeutic approach. “LLLT” specifically focuses on the use of laser light, while “PBMT” is the broader scientific term describing how light interacts with cells and tissues to influence biological processes involved in tissue recovery.

Both terms refer to light-based therapy that acts on cellular processes involved in local inflammatory modulation, tissue recovery, and healing.

The initial consultation with Dr Shikha Parmar requires up to 60 minutes where your condition is fully assessed along with your medical history. Dr Parmar will take a thorough history of your problem from its onset, through its progression to now. She will review any imaging reports pertaining to your problem, and may recommend further investigations. Dr Parmar will give you a detailed explanation of your problem, and will discuss our holistic approach and management plan including the utilisation of Low Level Laser Therapy (LLLT). If your condition is amenable to LLLT the treatment is commenced at the initial consultation. A medical consultation with Dr Shikha Parmar, GP, is billed and is rebatable through Medicare for patients who hold a Medicare card.

Yes. LLLT/PBMT has been used clinically in Europe for nearly 30 years and has been the subject of substantial published research. The literature includes double-blind studies, laboratory studies, randomised controlled trials, clinical studies and systematic reviews. The strength of evidence varies according to the condition being treated, treatment parameters and clinical context.

Published literature includes papers in journals such as:

  • Nature, Pain, PNS, Blood, BMJ, Spine, Muscle and Nerve, The Lancet, Circulation and BJSM
  • Around 30 LLLT papers published per month
  • Over 4000 laboratory studies and over 400 randomised controlled trials

Over 2,500 clinical studies and published research reports have investigated the use of LLLT/PBMT across a variety of health issues. In the LLLT dental literature alone, involving 370 studies, more than 90% of these studies have reported clinical value for laser therapy.

LLLT has been used in veterinary practices for decades. In recent years, professional sports teams have also begun utilising LLLT/PBMT.

In the last 20 years, 8 systematic reviews have reported findings in favour of LLLT/PBMT in selected clinical contexts, including:

  • American College of Physicians Guidelines include a “strong recommendation” for Low-Level Laser Therapy as a non-invasive treatment for acute, subacute & chronic low back pain. (2017) Click here
  • BMJ LLLT for chronic non-specific low back pain: a systematic review and meta-analysis of randomised controlled trials found “moderate quality of evidence” and “clinically important benefits” in the short term. (2016) Click here
  • BMJ sports medicine journal, systematic review of surgical and conservative interventions for frozen shoulder found “strong evidence” for LLLT. (2010) Click here
  • The BMJ clinical evidence recommendations for tennis elbow 2011 now include LLLT Click here
  • American Physical Therapy Association guidelines recommend LLLT for Achilles tendonitis. (2010) Click here
  • Lancet systematic review: “LLLT reduces pain immediately after treatment in acute neck pain and up to 22 weeks after completion of treatment in patients with chronic neck pain”. (2009) Click here
  • World Health Organisation Bone and Joint Task Force for neck pain reported Low Level Laser Therapy as “more effective than no treatment, sham, or alternative interventions”. (2008) Click here

Laser Therapy does not heat or cut tissue, unlike high intensity lasers. The question is often asked: “If it’s a laser, aren’t lasers used in surgical operations to cauterise tissue?” The answer is yes. High intensity surgical lasers can cauterise or cut tissue. The lasers used at Laser Pain Therapy are Class 3B low level lasers, a well-researched class in LLLT, designed for low-intensity therapeutic application. Our lasers use light energy to influence cellular processes rather than heat or cut tissue.

Regulatory bodies assess LLLT/PBMT devices according to intended use and device class. Device selection, dosing and clinical supervision are important for appropriate application.

For the past 30 years, Low Level Laser Therapy (LLLT) technology has been formally accepted in many parts of the world such as Canada, USA, Brazil, Europe, Scandinavia, Russia and Japan. Published research and clinical experience over this period support a favourable tolerability profile. LLLT/PBMT is non-invasive and generally well tolerated.

Industry has been using laser diodes for years in applications such as bar code readers, CD players, DVD players, laser printers and pointers. Some bio-stimulation laser devices have been listed as non-significant risk (NSR) devices in specific regulatory contexts.

Hundreds of research studies have investigated Laser Therapy in pain and tissue recovery settings. Laser Therapy is non-invasive and non-thermal. Over 400 LLLT clinical trials (RCTs) and over 2500 laboratory studies have been published. Comparisons with pharmaceutical anti-inflammatory medication depend on the condition being treated, study design and treatment parameters.

LLLT has also been investigated for tissue recovery processes, muscle fatigue, muscle damage and delayed onset muscle soreness, or DOMS.

Most patients tolerate LLLT/PBMT well. Patients may occasionally experience mild discomfort or aching after treatment. This is usually temporary and should settle within 24 to 48 hours.

LLLT/PBMT uses red and near-infrared light and does not use ionising radiation. No mutational effects have been observed from light with wavelengths in the red or infrared range and doses used within LLLT/PBMT in published studies.

Where a patient has known or suspected cancer, this requires medical assessment and appropriate management. LLLT/PBMT at Laser Pain Therapy is not used as a treatment for cancer.

The effects of LLLT/PBMT on cancer cells have been studied in vitro and in animal models, but these findings should not be translated into broad clinical claims about treating cancer or tumour behaviour in people. Treatment decisions are made according to the patient’s clinical context and medical history.

Similarly, laboratory findings involving bacteria or viruses can differ from clinical infection management. This section should not be read as a claim that LLLT/PBMT treats bacterial or viral infection. If infection is suspected, appropriate medical assessment and treatment are required.

Laser Therapy should be avoided in the following instances:

  • Over the womb for women in pregnancy
  • Over a cancerous tumour, primary or secondary (LLLT is not a treatment for these conditions)
  • Direct irradiation of the eyes

At Laser Pain Therapy, we use state-of-the-art, TGA-approved laser devices, applied by highly trained assistants. Our laser devices deliver red and infrared laser energy at selected treatment parameters to support the intended tissue response. With the application of up to 37 diodes (laser lights) across multiple devices, we support time-efficient treatment without compromising dosage or energy delivery. Unlike LED devices, our laser technology provides deeper penetration and more targeted tissue application.

Dr Shikha Parmar, an experienced GP with over 30 years in General Practice and 14 years of expertise in photobiomodulation therapy, leads our clinic, making her one of the most experienced doctors in this field. Treatment at Laser Pain Therapy is medically supervised, ensuring each patient receives a thorough assessment that takes into account not only their presenting condition but also relevant health factors, such as co-morbidities, medications, lifestyle, work, personal activity demands, and nutritional deficiencies. This holistic approach allows us to tailor care with LLLT at the core, supported by personalised advice.

Additionally, our treatment plans are finite, with clear goal-setting and regular progress reviews, supporting each patient to stay on track with their recovery plan and treatment goals.

At Laser Pain Therapy, we use advanced equipment with laser diodes, not LED lights. Unlike LEDs, laser diodes provide more focused light with deeper penetration, making them suitable for targeted musculoskeletal treatment.

Our state-of-the-art equipment features 37 laser diodes, allowing us to efficiently cover a larger surface area. This optimises treatment time and supports targeted energy delivery. Unlike devices that use just 2-4 diodes, our technology allows more time-efficient treatment delivery while maintaining the intended dose and treatment parameters.

The effects of LLLT are accumulative. For many patients undergoing a treatment program, improvements can be sustained when the condition is suitable and the recommended activity advice and rehabilitation plan are followed. Some patients notice early improvement, while others may not notice improvement until after 3 to 5 treatments. Most patients usually require 10-12 treatments.

More severe conditions will usually require more treatments than less severe injuries. Since each person’s condition varies in severity, Dr Parmar will determine after reviewing your condition how laser treatments may benefit you and how many you might require.

Your situation will be assessed after 6 treatments and if there has not been sufficient improvement after 6 to 8 treatments, LLLT will not be continued and alternatives will be considered for your future management.

You will need to follow precautions in order to avoid re-injury or the pain may return. Low Level Laser Therapy may help support tissue recovery processes, but activity modification and rehabilitation remain important for longer-term recovery.

Low level lasers do not generate perceivable heat. Therefore, when the laser contacts the skin, the patient should not experience burning as a result of the laser. Most people feel nothing at all while a few may feel a slight tingling or warmth during the treatment.

No. As Dr Shikha Parmar is a General Practitioner a doctor’s referral is not required.
