I hope she's okay!!!! Thankfully they ruled out the worst case senario. I have massive cluster headaches that strike at random. It's always on my right of left temple and I go blind in one eye (the eye thats on the same side as the headache) while it lasts. I've never felt any kind of pain like I have those, and let me tell you I'd take a normal migraine over these things anytime.
I'll keep Shannon in my prayers and hopefully they can find what is triggering the pain and fix it.
