I am experiencing mild pain on the left side of my head just an inch above the ear, when I chew I feel severe pain just like nerve there is pull apart, when I expose myself to direct sunlight I experience severe pain and someday especially at nights I experience severe headache in that area I am experiencing this problem since 3 to 4 months and also my throat remains dried up since 1 month but I drink sufficient water but I do not know whether it is related to this problem or not.
