Trigeminal neuralgia is a type of paroxysmal chronic pain that affects the face and is characterized by episodes of intense pain, akin to an electric shock. Typically, it occurs on one side of the face. This condition is related to the trigeminal nerve or the fifth cranial nerve, responsible for transmitting facial sensations to the brain. Any stimulation on the face, from brushing teeth to talking, can trigger this stabbing pain.

Although the origin of this functional disorder is unknown, it is associated with various peripheral and central causes. It is usually linked to irritation of the trigeminal nerve due to the compression of a blood vessel (artery or vein). In rarer cases, compression may be caused by a tumor. However, this situation occurs in only 0.8% to 3% of cases.

Moreover, there is minimal evidence linking trigeminal neuralgia to multiple sclerosis. Approximately 1-2% of patients with this nervous system disorder develop neuralgia, translating to 2-3% of cases of trigeminal neuralgia.

As for symptoms, we are talking about partial facial pain, but it can manifest in various ways: spontaneous attacks of pain triggered by any stimulus, pain accompanied by facial spasms, episodes of multiple attacks lasting days, weeks, or months, pain concentrated in a specific location, or some other pattern.

Intense oncological pain, previously untreatable, is one of the cutting-edge treatments in this field, thanks to ZAP-X. To put it in numbers, up to 30% of cancer patients experience pain at the time of diagnosis, but this percentage rises to 60-80% in more advanced stages. In this case, we refer to basal pain, breakthrough pain, neuropathic pain, or refractory pain. Thanks to this technology, patients can find an alternative treatment to alleviate pain throughout the entire process.
