The severe facial pain of a condition called trigeminal neuralgia is so unusual that people who have trigeminal neuralgia mistake it for a stroke. Trigeminal neuralgia is not a stroke. It is a medical condition that causes part of the face to be highly sensitive to touch and extremely painful even when it is not being touched.
Each side of your face obtains its sensory function through a nerve called the trigeminal nerve.
Trigeminal neuralgia is caused by damage or irritation of the trigeminal nerve, and this is what gives the condition its name.
Facial pain and stroke
Pain in the face is almost never the only sign of a stroke. Head pain can be a sign of stroke, but even when headaches are a signal of a stroke, the headaches are accompanied by other neurological problems.
