Hi there Maria and welcome to NeuroTalk.

I hope your pain isn't Trigeminal Neuralgia because I've had that myself, and I know how painful it can be.
I'll give you the link to the forum for that so you can meet some others with similar concerns : http://neurotalk.psychcentral.com/forum26.html

You might also be interested in posting in our diabetes forum, so here the link to that as well. http://neurotalk.psychcentral.com/forum53.html
