Thanks for the reply AAAAA and I would be interested to know the results of the MRI and CAT scan. I agree it can be frustrating for patients and doctors when it comes to figuring out the source for headaches. The brain is so intricate and mysterious. It must be so hard see your daughter suffer in pain for so long and I hope she can find a successful treatment. I watched a PBS show called the Plastic Brain - I can't remember the name of the doctor but he has a well known book out. He believes that we can influence positive or negative changes to our brains depending on our lifestyles. I don't want to hear you calling yourself names though.
