It is a type of chronic pain that affects the face, sudden burning or feeling of extreme shock. It usually affects one side of the face and the likely cause is a blood vessel pressing on the trigeminal nerve, one of the largest nerves in the head.

Treatment: Conventional painkillers such as aspirin, paracetamol and opioids are not usually useful to control facial pain and drugs must be used for the treatment of epilepsy such as carbamazepine, antiepileptic drugs that block nervous excitability reducing pain. and the frequency of pain discharges. Certain tricyclic antidepressants such as amitriptyline can also be associated. Surgery is aimed at relieving pressure on the trigeminal nerve and is reserved for cases that do not respond satisfactorily to drugs or when the side effects of medication are severe.
