Suggest Remedy For Constant Headaches

Hi I for the last couple of days I have been having bad head aches. I went to the doctor today and they said that I didn't have the symptoms of a migrain but they gave me an emitrex( I know I didn't spell that right) All that did was make me feel alittle light headed for like a hour and now I am right back at the beginning with a killer head ache.
