Tomorrow? Wow - that's WONDERFUL !! I'm so very glad you don't have a long wait and I'm even happier that you get to see a headache specialist.
Something hideous happened to a friend of mine's back in a skiing accident - he lives in Phoenix - and he went to the Mayo. I understand that's very different from headaches, CFS, epilepsy, but he and his wife were thrilled by the Mayo's doctors' and all the care.

Please do hurry back here as quickly as you can and let us know what happens during your appointment.
Many of us will be praying for you.
