Final answer:
Trigeminal neuralgia is a chronic pain disorder that causes severe, lancinating pain on the cheek. It is caused by compression or irritation of the trigeminal nerve and can be treated with medications, nerve blocks, or surgery.
Step-by-step explanation:
The symptoms described in the question are consistent with a condition called trigeminal neuralgia. Trigeminal neuralgia is a chronic pain disorder that affects the trigeminal nerve, which supplies sensation to the face, cheek, nose, and upper teeth. The pain is often described as severe and lancinating, meaning it feels like an electric shock or stabbing sensation. The specific location of the pain on the cheek, along with its severity, is a characteristic feature of trigeminal neuralgia.
Trigeminal neuralgia can be caused by various factors, including compression or irritation of the trigeminal nerve by a blood vessel, multiple sclerosis, or nerve damage. Treatment options for trigeminal neuralgia include medications to manage pain, nerve blocks, and in severe cases, surgery.
