Still relying on anti-neuropathic medicines like gabapentin, amitriptyline, or Qutenza to manage nerve pain? These medicines help many people, but they do not work well for everyone. Some people continue to have pain, while others find the side effects difficult to manage. Because of this, more people are exploring Cannabis for nerve pain as an additional treatment option under specialist care. This approach is becoming more common in the UK, with an estimated 60,000 to 75,000 patients receiving prescribed Cannabis-Based Medicinal Products (CBMPs).
CBMPs interact with the body's endocannabinoid system, a network involved in regulating pain and other important functions. CBMPs are thought to influence how the body responds to pain signals rather than target their underlying cause. In this article, you'll learn what neuropathic pain is, how CBMPs work, and their potential role in managing nerve pain.
Key Takeaways: Medical Cannabis for Nerve Pain
Neuropathic pain develops when damaged nerves send abnormal pain signals, often causing burning, tingling, numbness, or electric shock-like sensations that can affect daily life. Cannabis-Based Medicinal Products (CBMPs) may help some patients by interacting with the body's endocannabinoid system to influence pain signalling and inflammation, though they do not repair nerve damage. When symptoms persist despite conventional treatments or side effects become difficult to manage, a specialist assessment can help determine whether prescribed medical cannabis is an appropriate treatment option.
What Is Nerve Pain (Neuropathic Pain)?
Nerve pain, also called neuropathic pain, happens when nerves are damaged or do not work properly. According to the National Institute for Health and Care Excellence (NICE), it is caused by a disease or injury affecting the somatosensory nervous system. Unlike muscle or tissue pain, neuropathic pain starts in the nerves themselves. The damaged nerves send pain signals to the brain even when there is no new injury. Because this type of pain can be difficult to manage with standard medicines alone, some patients explore medical cannabis for neuropathic pain under the care of a specialist.
If you're new to this treatment route, it's worth first understanding how the prescription process works in the UK.
What Are the Causes of Nerve Pain?
Nerve pain can have many different causes, including:
Medical conditions: Diabetes, shingles, or multiple sclerosis
Physical trauma: Nerve compression, such as sciatica, or injuries from surgery or accidents
Toxicity: Chemotherapy treatment or excessive alcohol use
These underlying causes can be difficult to treat, so some people continue to experience nerve pain even after receiving treatment.
Symptoms of Neuropathic Pain
Neuropathic pain often feels very different from pain caused by a cut or muscle injury. The symptoms can be unpredictable and may vary from person to person. They can also affect sleep, daily activities, and overall quality of life.
According to the NHS, Common symptoms include:
Burning, stabbing, or electric shock-like pain
Tingling, numbness, or "pins and needles"
Increased sensitivity to touch or temperature
Muscle weakness or poor coordination
Managing these symptoms can be challenging. For some people, prescribed Cannabis-Based Medicinal Products (CBMPs) may be considered as part of a wider treatment plan. Next, we'll look at how CBMPs work inside the body.
How Do Cannabis-Based Medicinal Products (CBMPs) Work for Nerve Pain?
Researchers believe CBMPs may help some people manage neuropathic pain by interacting with the body's endocannabinoid system (ECS). Patients are usually guided through this process by a medical cannabis clinic, which assesses suitability before any prescription is issued. This system helps regulate pain, sleep, mood, and inflammation. While CBMPs do not repair damaged nerves, they may influence how the body responds to pain. Here's what may happen when prescribed CBMPs are used.
1. Entering the Endocannabinoid System (ECS)
Every person has an endocannabinoid system (ECS), a network of receptors that helps regulate pain, sleep, and mood. According to the Pain Relief Foundation (UK), when prescribed Cannabis-Based Medicinal Products (CBMPs) are taken, cannabinoids such as THC and CBD travel through the bloodstream and interact with these receptors.
2. Locking Into the Receptors
You can think of cannabinoid receptors as tiny locks on your cells. THC and CBD act like keys that fit into these locks. THC mainly interacts with CB1 receptors in the brain and spinal cord, while CBD mainly interacts with CB2 receptors, which are found in the immune system and peripheral nerves. This interaction is thought to influence how the body processes pain and inflammation.
3. Quieting the Hyperactive Nerve Signals
When THC interacts with CB1 receptors, it may affect the release of brain chemicals involved in pain signalling. This may reduce the strength of pain signals travelling to the brain, making symptoms feel more manageable for some people.
4. Suppressing Neural Inflammation
CBD may also influence inflammatory processes associated with nerve damage. Although research is still developing, some studies suggest this may help reduce irritation around affected nerves in some people. This is one reason medical cannabis for chronic pain continues to be studied as a treatment option when conventional therapies have not provided enough relief.
5. Rewiring Pain Perception in the Brain
Finally, THC may also influence how the brain processes pain signals, making symptoms feel more manageable for some patients. This may also translate into better sleep or reduced sensitivity to touch.
Signs It's Time to See a Specialist for Nerve Pain
Persistent or worsening nerve pain should never be ignored. This infographic highlights key warning signs that indicate it's time to seek professional care, including pain lasting more than three months, burning sensations, disrupted sleep, difficulty with daily activities, medications that no longer provide relief, and troublesome treatment side effects. Recognizing these symptoms early can help you receive an accurate diagnosis and effective nerve pain treatment before the condition significantly impacts your quality of life. Many patients considering Cannabis for nerve pain choose to book a specialist consultation for a full assessment.
Conclusion
Cannabis-based treatments, including CBD, are increasingly being explored for neuropathic and chronic pain when standard therapies fall short. However, outcomes vary, making professional guidance essential before starting any treatment. Leva Clinic is a specialist medical cannabis clinic that provides specialist-led assessments where doctors review your symptoms and medical history to design a tailored, regulated care plan focused on safety and effectiveness, helping you make informed decisions about your pain management journey.
