Cindy,
I have had some recent problems with neck pain and stiffness which I'm sure is from radaition and every now and then it isn't just stiffness but cramping, which is very painful.

I've also read the stuff about "chemo brain" and I'm sure it's very real. I have to say, though, that although I'm not a neuropsychologist, I have a little training in that area and the memory problems you describe--especially the confabulation (a fancy word for having real-seeming memories of things that never happened) sound unusual and something to be concerned about. Even with that symptom, though, it doesn't mean he necessarilly has a tumor.
