What is the trigeminal nerve?
The trigeminal nerve is the main sensory nerve of the face, which transmits signals from the skin, muscles, teeth, eyes and mucous membranes to the brain. It has three branches: the ophthalmic, maxillary and mandibular. Each is responsible for a specific area of the face, so the pain can be concentrated in different areas – from the forehead to the chin.
Trigeminal neuralgia is a chronic condition that manifests itself in sudden attacks of pain, which patients describe as “electric shock”, “shooting”, “sharp cutting”. Attacks can be single or serial, sometimes occurring dozens of times a day. There are two types of neuralgia:
- Primary (idiopathic) – when the nerve is irritated due to contact with a vessel that compresses its root.
- Secondary – when the pain is caused by another disease: a tumor, multiple sclerosis, the consequences of injuries or infections.
This is one of the most painful neurological disorders that requires clear diagnosis and comprehensive treatment.
