I am having pain in the left side of my head, above and below eye, nose, jaw and teeths, ear  only in left side. The pain is throbbing and severe. It is mainly triggered by noise, talking, smiling, travelling. I am a student and studying 12-13 hours a day usually in front of a screen is my daily schedule. Most of the time I m having headache which I can tolerate now. But this kind of pain is intolerable. Please suggest what should I do to get rid of it.
