Just a little worried

[nitewind]

About a month ago, I started having headaches. They are in the back of my head and it's a very "heavy" feeling. Sometimes when I get them my eyes go "funny" on me, not really dizzy just hard to get things in focus. My onc acuses me of always having something new going on so I decided to give it a month before I told him about the headaches. When I did tell him, he didn't make much of it, just said well we will watch and see. That was last Friday.
I made an appointment with my primary care doc for tomorrow. He has always been very very thorough and I'm sure he will check this out too.
I also have an appointment with my eye specialist next Monday, I've developed macular degeneration and thinking maybe this is causing the headaches (I hope).
I'm nearly finished with my year of herceptin so naturally I'm thinking, uh oh, maybe it's brain mets. Trying real hard to keep that thought in the back of my mind but not doing so well with that. I know that Herceptin can't cross the blood/brain barrier. Anyway, I'm just a little on edge and would appreciate any good thoughts from you lovey girls. Also, anyone with mets to the brain, did you have symptoms of any kind?
I appreciate your input and prayers.
Hugs
