I am currently taking Anastrozole and I am having headaches in the top of my head frequently. I do have a schedule appointment with a Neurologist January 22, 2015 to help me understand the nature of these headaches. I had surgery in 2013 for breast cancer and six months mamographys have all been benign.Major concern about what I have been reading my headaches are "ice pick headaches). Try to help me understand what I am experinging. Thanks!!
