i frequently get left side head ache, around the left eye , behind the ear, upper left back part of the neck ., and the rear left part of the head . infact even when I have no head ache, if I press a particular point on my rear upper part of my head( about 2 above the left ear) , I feel a mild pain . I am fed up with this head ache which some times makes me vomit also. kindly suggest some remedy and help me.
