question: I m a 38 year old male in great shape taking no medications. Approximently two weeks ago I was working out when I had a wearied feeling at the base of my skull when I came down off the pull up bars from doing an ab workout it made me a little light headed but I completed the workout, there has never been pain at the base of the skull where it meets the neck it was just a feeling like when your ears pop. I have had mild to bad head aches every day since worse in the afternoon or after working out or working hard. Should I be concerned?
