The back of my head has been hurting suddenly almost daily now. it feels hot inside of my head and like blood is flowing through it. ?

Doctor should check: Most people get a headache at some time, such as from colds, infections, lack of sleep, too much driving, long hours on the computer, stress at work, etc... Over-the-counter options include Tylenol, Motrin or Advil, Aleve, Excedrin and their generic brands. A bad or increasing headache, recurrent headache (as in this case), weird headache, or with other worrisome symptoms should be evaluated now.
