Sally - yes nerve pain can be excruciating!
I haven't had it that bad for long periods though- only for a few seconds, then it goes, then comes again (a bit like contractions!) But never for more than a few minutes all up thank God!

But yes, when I had it in my head, I was worried.
If I hadn't of had a clear MRI and CT scan 7 months prior, I would have been at the Dr. asap looking for an annuerism! (sp?)
