I have been having headaches

Hopefully and most likely it's musculoskeletal- have you tried massage or do you take Tylenol?
I don't mean to oversimplify or minimize your symptoms, but on the 2 occasions I've been dx'd & treated for brainmets I never experienced headaches. Each time I would meet with my RadOnc he would ask if I was experiencing headaches, blurry vision, seizues, balance issues. The answer was always No, thankfully, but I did ask him to elaborate the type of headache I might keep an eye out for. He said "one that doesn't resolve with Tylenol."
I'm hoping for the best for you, but definitely ask your Onc next time you have an appointment. If you're feeling uneasy, I don't think it's unreasonable for you to put a call in to your doc for their opinion.
Keep the Faith~
