Trigeminal neuralgia: a pain patients describe as electric shocks

What is trigeminal neuralgia

The trigeminal nerve carries sensation from the face to the brain. When its functioning is disrupted, intense facial pain arises suddenly and recurs over time. It is precisely this pattern, brief and recurring episodes on one side of the face, that defines this condition and distinguishes it from other facial or dental pain.

As the article notes, this is one of the most painful conditions described in medicine. Many people experience it as disabling, to the point of affecting such everyday actions as eating, speaking or washing. You can find details of when surgery is indicated on our page about trigeminal neuralgia.

Why the pain arises

In most cases, the origin is contact between a blood vessel and the nerve at its exit from the brainstem. Over the years, that sustained pressure can damage the protective sheath around the nerve fibre and cause the nerve to transmit pain signals abnormally. This is why completely normal stimuli such as smiling, chewing or brushing the teeth can trigger episodes that patients compare to electric shocks.

However, vascular compression is not the only possible cause. Sometimes the condition is associated with other neurological diseases, such as multiple sclerosis, or, less frequently, with lesions affecting the course of the nerve. This underlines the importance of a specialist assessment to identify the precise origin before deciding on treatment.

An impact that goes beyond the pain

The characteristic symptom is very intense pain, almost always on one side of the face, lasting from a few seconds to a few minutes and triggered by specific stimuli such as shaving or touching certain areas. It tends to appear in adulthood and in older people, although it can occur at any age.

Recognising this pattern is key to directing the diagnosis correctly and avoiding unnecessary dental treatments that delay identification of the real problem. Fear of a new crisis affects eating, social life and work, and in the most severe cases can lead to isolation, anxiety or significant loss of well-being. The approach therefore goes beyond symptom control and aims to restore the patient's independence.

Current neurosurgical treatments

Advances in recent years have notably improved prognosis. The combination of high-definition neuroimaging, highly precise microsurgical techniques and a better understanding of the disease allows the cause of the pain to be pinpointed and increasingly personalised, safer therapies to be offered. Many patients who had lived for years with debilitating pain recover a normal life.

In our team, these options sit within functional neurosurgery and the management of movement and pain disorders. The goal, as Dr. Roldán emphasises, is to tailor treatment to each individual to recover well-being, independence and quality of life.
