Neuropathic Facial Pain

Neuropathic facial pain is a chronic neurological condition characterized by severe, persistent pain in the face. This type of pain results from damage or dysfunction in the nervous system, often affecting the trigeminal nerve, which is responsible for providing sensory information and controlling facial muscle movements. Neuropathic facial pain can be highly debilitating, significantly impacting an individual’s quality of life and daily functioning. Common conditions associated with neuropathic facial pain include trigeminal neuralgia, postherpetic neuralgia, and atypical facial pain. Treatment options typically involve medications, nerve blocks, and in some cases, surgical interventions to alleviate pain and improve overall well-being.

What is Neuropathic Facial Pain?

Neuropathic facial pain is a type of chronic pain that affects the face due to damage or dysfunction in the nervous system. It can be associated with various conditions, each presenting different symptoms and causes.


Common symptoms of neuropathic facial pain include:

  1. Sharp, shooting, or burning pain in the face, often triggered by everyday activities like eating, speaking, or touching the affected area.
  2. Intermittent or constant pain that can be localized or spread across one side of the face.
  3. Sensitivity to touch or temperature changes in the affected area.
  4. Muscle weakness, numbness, or tingling in the face.


The causes of neuropathic facial pain can vary depending on the underlying condition:

  1. Trigeminal neuralgia: Often caused by compression of the trigeminal nerve by a blood vessel, leading to severe, episodic facial pain.
  2. Postherpetic neuralgia: Occurs as a complication of shingles (herpes zoster) infection, resulting in persistent nerve pain after the rash has healed.
  3. Atypical facial pain: The cause is often unclear, but it may be related to a combination of nerve injury, psychogenic factors, or other unknown triggers.


Preventing neuropathic facial pain depends on addressing the underlying causes and risk factors. Some general strategies include:

  1. Maintaining good overall health: Regular exercise, a balanced diet, and stress management can help support a healthy nervous system.
  2. Timely treatment of infections: Early treatment of shingles or other infections can reduce the risk of developing postherpetic neuralgia.
  3. Regular medical check-ups: Routine visits with healthcare professionals can help identify and address potential issues before they become more severe.

In some cases, neuropathic facial pain might not be preventable due to genetic factors or unavoidable nerve damage. However, early diagnosis and appropriate treatment can help manage symptoms, improve quality of life, and reduce the risk of further complications.

Medical Marijuana as a Treatment for Neuropathic Facial Pain

Medical marijuana has shown potential in managing various types of chronic pain, including neuropathic facial pain. It can help alleviate symptoms and improve the quality of life for those affected by this condition.

How does medical marijuana help?

Medical marijuana may aid in managing neuropathic facial pain through the following mechanisms:

  1. Pain relief: Certain cannabinoids have demonstrated analgesic properties that may help reduce chronic neuropathic pain.
  2. Anti-inflammatory effects: Medical marijuana can help decrease inflammation, which may contribute to nerve pain.
  3. Muscle relaxation: Medical marijuana can potentially help reduce muscle spasms or tension associated with neuropathic facial pain.
  4. Anxiolytic effects: Medical marijuana may alleviate anxiety or stress, which can exacerbate pain symptoms.

Cannabinoids and Terpenes for Neuropathic Facial Pain

Some specific cannabinoids and terpenes may be particularly effective in addressing neuropathic facial pain:

  1. THC (tetrahydrocannabinol): THC possesses pain-relieving and anti-inflammatory properties, which could help manage discomfort and inflammation associated with neuropathic facial pain.
  2. CBD (cannabidiol): CBD has demonstrated significant pain-relieving, anti-inflammatory, and anxiolytic effects without causing psychoactive side effects, making it a promising option for symptom management in patients with neuropathic facial pain.
  3. Beta-caryophyllene: This terpene has demonstrated anti-inflammatory and analgesic properties, potentially providing additional support for individuals with neuropathic facial pain.
  4. Linalool: Linalool, a terpene with a floral scent, possesses sedative, anxiolytic, and antispasmodic properties that may help alleviate pain and muscle tension in individuals with neuropathic facial pain.

It is essential to consult with a healthcare professional experienced in cannabinoid medicine when considering medical marijuana as a treatment for managing neuropathic facial pain-related symptoms. They can help determine the appropriate strains, ratios of cannabinoids, and dosages tailored to an individual’s specific needs and circumstances. Further research is needed to fully understand the long-term effects and efficacy of medical marijuana in managing neuropathic facial pain symptoms and side effects.

Dosage and Consumption Methods

Recommended dosage:

Figuring out the right dose of medical marijuana can be hard because people’s reactions to cannabinoids and terpenes can be very different. Factors such as the specific condition being treated, the patient’s weight, metabolism, and prior experience with cannabis all play a role in determining the right dosage.
Most of the time, it is best to start with a low dose and slowly increase it until you get the effects you want while minimising any possible side effects. For patients who are new to medical marijuana, starting with 2.5–5 mg of THC or CBD and slowly titrating upwards is often advised.

However, consulting a healthcare professional experienced in medical marijuana is essential to developing a personalised dosing plan tailored to the patient’s needs.

Consumption methods:

There are several methods of consuming medical marijuana, each with its advantages and disadvantages. Some common consumption methods include:

  1. Inhalation (smoking or vaping): Inhalation provides rapid onset of effects, usually within minutes, making it suitable for patients requiring immediate relief. However, smoking may pose respiratory risks, while vaping has been associated with lung injuries in some cases.
  2. Oral ingestion (edibles, capsules, tinctures): Ingesting medical marijuana provides longer-lasting effects compared to inhalation but has a slower onset, typically taking 30 minutes to 2 hours for effects to be felt. This method is suitable for patients requiring sustained relief but may require careful dosing to avoid overconsumption.
  3. Topical application (creams, balms, patches): Topicals can provide localised relief for conditions such as arthritis or skin disorders without producing psychoactive effects. The onset of action and duration of effects can vary depending on the product formulation and individual absorption rates.
  4. Sublingual administration (tinctures, dissolvable strips): Sublingual products are absorbed through the mucous membranes under the tongue, providing rapid onset of effects without the need for inhalation or ingestion. This method offers discreet consumption and precise dosing.

Obtaining a Medical Marijuana Card

Why get a medical marijuana card?

Getting a medical marijuana card is helpful for patients who are looking for other ways to treat their conditions.

  1. Legal protection: A medical marijuana card allows patients to possess, use, and in some cases, cultivate cannabis for medical purposes, within their state’s legal limits.
  2. Access to quality products: Medical marijuana dispensaries offer a wide range of tested and regulated cannabis products, ensuring patients receive safe and effective medication.
  3. Tax savings: In some states, medical marijuana patients are exempt from certain taxes applied to recreational cannabis sales.
  4. Professional guidance: Medical marijuana cardholders have access to healthcare professionals who can provide personalised recommendations, dosing advice, and ongoing support.

How to apply:

The process of obtaining a medical marijuana card varies by state but generally involves the following steps:

  1. Consult with Marijuana recommendation doctors to determine if medical marijuana is appropriate for your condition and obtain a written recommendation.
  2. Complete an application with the required documentation, including proof of residency, identification, and the healthcare professional’s recommendation.
  3. Submit the application to the appropriate state agency, along with any required fees.
  4. Await approval and issuance of the medical marijuana card.

Risks and Side Effects

Potential risks:

While medical marijuana can offer relief and improve the quality of life for many patients, it also carries certain risks and side effects. Some potential risks associated with medical marijuana use include:

  1. Dependency and addiction: Although the risk of addiction is considered lower than that of opioids or alcohol, some individuals may develop a dependency on cannabis.
  2. Impaired cognitive function: THC, the primary psychoactive compound in cannabis, can impair memory, attention, and reaction times, particularly with prolonged or heavy use.
  3. Respiratory issues: Smoking cannabis can cause respiratory problems, including bronchitis and lung irritation. Vaping has also been linked to lung injuries in some cases.
  4. Mental health concerns: High doses of THC or predisposition to mental health disorders can lead to increased anxiety, paranoia, or exacerbate existing mental health conditions.
  5. Drug interactions: Medical marijuana may interact with other medications, either enhancing or diminishing their effects. It is essential to discuss potential drug interactions with a healthcare professional before starting medical marijuana therapy.


Medical marijuana might not be right for every patient, especially those who already have certain health problems or risk factors. Contraindications to medical marijuana use may include:

  1. Personal or family history of substance abuse or addiction
  2. Severe liver or kidney disease
  3. Severe cardiovascular disease
  4. Pregnancy or breastfeeding
  5. History of psychosis or other severe mental health disorders
  6. Allergies or hypersensitivity to cannabis or its components

Legal Status

Where is it legal?

In the United States, the laws about medical marijuana are always changing. Currently, over 30 states and the District of Columbia allow its use under certain conditions. Each state has its own rules and a list of medical conditions that are allowed to use medical marijuana.

Even though some states have made medical marijuana legal, it is still illegal at the federal level because it is a Schedule I substance under the Controlled Substances Act.

This difference between state and federal laws can make it harder for medical marijuana patients to get jobs, find housing, or travel across state lines, among other things. Patients should research their state’s guidelines and remain aware of potential legal risks.


Medical marijuana could help relieve symptoms and improve the quality of life for many people with long-term or debilitating illnesses.

When thinking about this treatment option, it’s important to know the right dose, how to use it, how to get a medical marijuana card, possible risks, side effects, and legal status.

Work closely with a doctor or nurse who knows a lot about medical marijuana to find out if it is a good and safe choice for your needs.
