I have late onset CAH and the common denominator for most of us seems to be headaches. I am curious where the headaches seem to be located for other people. With me the headache seems to start at the base of my skull in my upper neck. The headache seems to progress from there to eventually being my whole head. My brother is in the process of being assessed for CAH (late-onset) and we were comparing notes last night about the headaches. My brother also said his headaches start at the base of his skull too. Coincidence? I don't think so! I would really appreciate comments from others regarding their headaches. Thanks Susan A.
