It's a condition that causes excruciatingly painful sensations to your face, similar to an electric shock. It's not rare, and it's often misdiagnosed as dental pain or a sinus issue.
The trigeminal nerve carries sensation from your face to your brain.
"And when it misfires or it doesn't function right, it gives intense shocks of pain. And the pain can be described as the worst pain ever," says Dr. Richard Zimmerman, a Mayo Clinic neurosurgeon.
