Hello,
So sorry about your currect condition. Below is what I was able to gather for you from the internet. It's definitely alarming and you should look into it:

"While Lamotrigine can be used to manage neuropathic pain, including peripheral neuropathy, it's important to be aware of potential side effects, especially for individuals with pre-existing peripheral neuropathy.
Common Side Effects of Lamotrigine:
Skin rash: A significant concern with lamotrigine is the potential for skin rashes, which can sometimes be severe. Any new or worsening rash should be reported to your doctor immediately.
Dizziness: Dizziness and lightheadedness are commonly reported side effects.
Headache: Headaches are another common side effect.
Double vision: Some individuals may experience double vision or other visual disturbances.
Lack of muscle coordination: This can manifest as clumsiness or unsteadiness.
Nausea and vomiting: Stomach upset is a potential side effect.
Somnolence: Feeling drowsy or excessively sleepy is a possible side effect.
Less Common but Important Side Effects:
Mood changes: Lamotrigine can affect mood, potentially leading to depression, anxiety, or agitation in some individuals.
Suicidal thoughts: In rare cases, lamotrigine may increase the risk of suicidal thoughts or behaviors.
Aseptic meningitis: This rare but serious side effect involves inflammation of the membranes surrounding the brain and spinal cord. Symptoms can include fever, stiff neck, headache, and sensitivity to light.
How Lamotrigine Might Interact with Peripheral Neuropathy:
Worsening of neuropathic pain: Although lamotrigine is sometimes used to treat neuropathic pain, it could potentially worsen pain in some individuals with pre-existing peripheral neuropathy.
Sensory disturbances: Lamotrigine itself can cause sensory changes like numbness, tingling, or burning, which might overlap with or exacerbate existing neuropathy symptoms.
Important Considerations:
Dosage adjustment: Starting with a low dose and gradually increasing it, as recommended by your doctor, is essential to minimize the risk of side effects.
Drug interactions: Lamotrigine can interact with other medications, potentially affecting its effectiveness or increasing the risk of side effects. Be sure to inform your doctor about all medications you are taking.
Monitoring: Regular follow-up appointments with your doctor are crucial to monitor for side effects and evaluate the effectiveness of lamotrigine in managing your pain."

Wishing you the best.
Take care and have a serene day,
