I have had a headache everyday 24 hours a day for 8 years (im now 24). Im so use to it that I do function normally. I had sinus surgery at 17 because my sinuses were messed up(thinking due to a blow to a face on my cheekbone from a guy I was dating at the time) but the same headache all the time no one thinks its because of sinus disease. I also dont have nasal drip and all that other stuff. I got raynauds when I was 15(which is a disorder where my blood flow doesnt circulate in my fingers and toes in the cold and turn white and blue) and at 17 I started becoming allergic to aspirin (which I never was before). I stopped going to dr's because they really cant offer me anything. The surgery only caused complications. My white and red blood cell count is normal. I do not have an infection in my immune system. My mom though had Heart disease, Kidney disease, vitaligo, athritis, gout, thyroid disease and the list goes on! I have often wondered if I had an autoimmune disease but havent been diagnosed with any. The dr's ive been to have just blown me off. I also had a huge cyst on my breast last year that was infected which had green puss coming out! Its just weird I have all these little problems and have NEVER had the answer for it! I know I dont have cancer, HIV, diabetes. Im not sure why the pain never leaves. When I drink anything but water, the pain intensifies. Its moderate now (much worse when it first started) and I dont even tell anyone now because people dont believe I REALLY have pain in my head everyday. Its not really like a migraine though. Sometimes I have a migraine on top of it. Its more facial pain.
