Sorry to hear you've got pain in your face, amongst other things going on. I just wanted to let you know that I had numbness to prior to surgery. May 2008 I woke up one day and was completely numb down my right side, not just my face, my body as well. After about a week my body came back to normal, but my face stayed numb until surgery in March this year. Everything was numb, the roof of my mouth, half my tongue, my ear, and I couldn't feel anything on my eyeball. Following surgery everything is back to normal which was a shock. I figured my facial nerve had been stretched (or whatever was going on with it) so much that it was damaged forever. Not so apparently! Although I must say getting the feeling back overnight in your face after 10 months without is a really really weird sensation. It was all super sensitive for a couple of days. As for the body - doctors think because I had such a substantial cyst inside my tumour, that it grew big all of a sudden, and at the same time as stretching my facial nerve, it hit my brainstem and caused that half of my body to become numb temporarily. Tres weird.
I hope your numbness doesn't get any worse - keep talking to the docs about it. In particular keep an eye on your eye (that sounds weird by you know what I mean!). If you lose feeling in your eye, you can't tell if any foreign objects are in there and that can lead to infections and nastiness.
I'm sure there were at least another couple of people on here who had numb faces - hopefully they'll chime in. And I'm sure there were some with facial pain - although, and I could totally be wrong... I did think that was a bit more meningioma related?
