Hi LaurenJ14,
there is something called Trigeminal Neuralgia which can cause pain in the nerves of the face, and while we can't give medical advice,
I would encourage you to speak to your doctor about this occurrence (if you haven't already) as it sounds as if it's something new to you and you want to make sure that you always report any new or worsening symptoms.
Meanwhile, there are articles that have mentioned this that might interest you.

If you can, please keep us posted on how you're doing! Janus
