Thanks for your response and for the medication suggestion. I have been looking at the side effects of Gemzar, his chemo drug and severe headache isn't supposed to be one of them. Although, before that he was on Avastin, which that has a major side effect of headaches.
Good luck to you. I hope your headache goes away. It doesn't seem like a lot of others suffer from headaches unless they are on Avastin.
I went to the natural supplement store. They recommended a couple vitamins to be used together. I can send those names to you if you are interested. One of them was B-6, can't remember the other one, but have it at home.
How have they treated your brain tumor? My dad hasn't been a problem since they did the whole brain and gamma knife.
Good luck.
