Im 17 years old female and for the past year I have been having horrible headaches, mostly in the evening or night time, two or three times a week. These headaches are not just your normal headaches, sometimes they even bring me to tears. Nothing seems to help, pressure, tylenol, nothing. It feels like pressure, or fullness. Its only on one side of my head at the time, but it vaires. Lately things have seemed to gotten worse, when I bend over my head feels tight, I get nautious and lightheaded, feel like im going to pass out. Ive also been getting chest pain on my left side, and last week my jaw was hurting. Im a volunteer firefighter, and I know some of these things are not normal, but I dont know if its something to go see a doctor about. Please, someone help me?
