That is crazy. trigeminal neuralgia. I had ask my doctor a year ago about those very symptoms. When I would touch my left cheek, especially in the morning when in the shower, I would have what I would describe to my wife as lightning bolts going from my cheek up through my left eye. Left side only. The doctor said there is a group of nerves that could get sensitive but did not give it a name. He said if it got worse they could do  scan or something.

It has mostly went away. Enough so that I did not even think about telling the new doctor. But the symptoms fit to a T.
