Hello @annco2709 and welcome to Mayo Clinic Connect. The sudden onset of symptoms surely has you concerned and anxious for good reason.

You will notice that I have moved your post into an existing discussion on Trigeminal Neuralgia, which you can find here: https://connect.mayoclinic.org/discussion/trigeminal-neuralgia-2273cc/

I did this so that you may more easily connect with others who have had a similar experience to what you described. Members such as @jmb73 @larryg333 and @paulboe may be able to come in and share more about their experience with you.

Trigeminal neuralgia is a condition characterized by pain coming from the trigeminal nerve, which starts near the top of the ear and splits in three, toward the eye, cheek and jaw, which seems to align with where you have experienced the pain.

When is your MRI? Are you getting an relief from the Gabapentin?
