Hello Shaunna ..... welcome to NeuroTalk.

I am very sorry that you are suffering from this symptom. I too have had it, once, and I thank the Lord that it's not recurred. I was treated with a different antiepileptic medication to Dilantin, but I ended up with a course of cortisone to rid myself of that terrible pain. Maybe that's something to think of if the symptoms continues much longer.

May I suggest that you have a look at our Trigeminal Neuralgia Forum because the pain is the same, no matter what the cause.

This is a really good thread for explanations:

... and there are more up in the stickies as well.

Here's the link to that forum. Do go have a read, even if you don't post.

I hope it eases soon for you.
