Hello, I've been having headaches in my forehead and eyes for the past week since I got home from a vacation where I spent the 3 days in 100+ degrees. It's worrisome to me because I have never had this kind of headache, like when you drink something cold, and it is low grade all the time, but peeks about 2-3:00 every day, and lasts for at least 3 hours. Advil usually kicks it, but I do not like taking meds and I have stopped taking them (break time). Yes, I have a great deal of stress, and a failing thyroid.
