Headache in different spots-behind eyes, above temple, in back/down back of neck. Had 2CTscans recent for head injury. Would they have seen a tumor?

Concussion. Some people may have a post-concussive/traumatic headache. If the headache is accompanied by other symptoms (tinnitus, difficulty concentrating, irritability) then you might have post-concussion syndrome. Improvement in symptoms is based on many factors including severity and location of the concussion. See a neurologist for evaluation. http://www.webmd.com/brain/post-concussion-syndrome.
