Well on the topic of headaches I know what it is like to get them. When my cortisol is low over a period of time (like when my blood work comes back high) I often notice a signifcant increase in the number and intensity of the headaches that I get. I firmly believe that they are related to my cortisol levels. No doctor has ever confirmed it and several of my endos have even referred me to a neurologist to check check for abnormalities in my brain. Often they crop up in times of high stress. Hope that this helps.
