Hi Emelie, how are you now?
Good suggestions from others, especially about getting tested to rule out any unwanted possibilities.
I wonder if the headaches might be partly due, as someone's already said, to dehydration. I find some mornings, I wake up with a headache and a particularly dry nose; the two things seem to go together. The Herceptin is known to interfere with production of the fine hair cells in our sinuses, isn't it. What helps to avoid the headache for me, is applying Vaseline (do you call it that in the States? Petroleum jelly) to the inside of my nostrils last thing at night. I think this helps moisturise the air as it passes through. That's my theory anyway. And you can get these things that put moisture into the air...chemo brain won't give me the name....aaaagh....help! Whatever that's called, it might help as well. Just asked husband - HUMIDIFIER!
Best wishes
