I'm so sorry that I'm unable to answer your question Annette, but I see BMW has given you some excellent advice. I wanted to welcome you to NeuroTalk anyway.

It sounds like your sister has been going through a really horrid time, and although she doesn't have trigeminal neuralgia, I was wondering if it would be worthwhile posting your question in that forum anyway. You never know when some-one else may have gone through something similar.

In case you haven't found it, here's the link: http://neurotalk.psychcentral.com/forum26.html
