My wife is experiencing headache since last one week. At times severe and at times close to nonexistent. The location is left side of the head, a bit top of the ear. It has a particular point on that area where when pressed with two fingers, the pain has a location. When severe, it stretches to the entire head. What could be the cause? She has no problem be it appetite, motion, vomiting, head spin, etc. Please advise. Thank you. Soumyajit Kundu
