I have migraine but lately i have frequent headache on front, back head and one side. every morning my head hurts when i wake up and i have headache almost every day. could it be brain tumor? and there is part of my head middle always in pain.

Need to examine: It is not feasible to provide a meaningful opinion without examining you, however, brain tumor is not high on the list of suspected lesions. One item to consider is that you may be grinding your teeth in your sleep and muscle tension is causing pain. You may start with your dentist to try a mouth guard at night. Wish you good health!
