radmom: I don't know if I buy into the doctors trying to tell you there is no connection between your radiation protocol and your post-radiation dizziness and headaches. Before I had my meningioma removed, I told the radiation oncologist that I had constant burning in my left nostril. He said that wasn't a symptom associated with the meningioma on the left side of the sphenoid wing of my brain. Well, he was wrong because once it was removed, a year and a half ago, I haven't had the burning sensation since. It actually was a direct cause.
