There  are  two main  categories  of headache  pain that  you  should be  aware  of.

Primary Headaches  –  These  are  the  headaches  most  of us  experience  on a  day-to-day basis.  They are  called  primary headaches  because  the  pain is  not  a  symptom  of another physical  disorder.  Ironically,  they are  often  called  “benign”  headaches, although  headache sufferers  would classify them  as  anything  but  benign.

Secondary Headaches  –  This  category of headache  includes  any  headache  that  is  the symptom  of another  physical  disease  or disorder.  Secondary headaches  can  be  caused by such frightening  diseases  as  aneurysms,  blood clots,  infections,  tumors  or a  high  fever,  as well  as  others.
