I have had a headache on and off for the past 13 days. Its been really hard to get anything done. I have never had a headache this long in my whole 31 years. Anywho I just wanted to know what has caused the headaches you have had? My doc sent me to get a CT scan, I have had my urine ran, I am not preggo, and I guess the only thing left is blood test? She gave me migraine pills but to me its dangerous to take pain meds and not fix the real issues. My next step is droppings gluten from my diet again and or an ED. I was just wondering because people are always more helpful to me then doctors who seem to only want to put people on drugs but never fix what the real issue is. What has caused your headaches???
