Hi Lisa, I agree with Lainy, could be just about anything. I personally over 2 years ago had a MRI done do to headaches and it turned out to be nothing cancer related. If it has not gotten better within a week, I would get checked for a possible sinus infection first of all. My daughter has had 3 sinus infections in the last two months just because of weather changes. Talking about weather changes, it is going from spring to deep freeze 20's tonight, crazy hey? And what about the polar region and what global warming has done today. Fatigue , worrying of the possibility, and stress may also cause phatom symtoms as well.
