is this migraine or a brain tumor??

hi guys i new here in healingwell.com.. and i would like to share my experience.. im really not sure if this is migraine because since i was a kid i never been to the hospital.. but i'm not afraid of the doctors..

i do experience headaches since i was 14 years old and now im 21.. every time i would have my headache a would suspect 2 things. 1) i skip my meals, 2)because of the heat outside.. and every time the headache attacks the first thing that i would do is to, EAT, 2nd is to take a bath then after that i really want to sleep in a very dark and silent room.. but if i can't sleep the last that i would do is to force myself to VOMIT, i will try the gag reflex where i will put my finger inside my mouth until i can feel that i will puke.. so yucky but that's the time that i can feel the headache will lessen.. if you will asked me why i didn't drink my medicine it is because the medicine has no effect on me.. when i was a kid i will always drink 2tablets or 1000mg of mefenamic to lessen my migraine.thats why today my body would not react on the medicine..

can you guys experience this also?? thanks for answering my question.. godbless us all..
