I'm really worried

I've been with a headache for two weeks, and it doesn't go away at all

I tried all kinds of headache pills and they don't seem to help! I went to the hospital 4 days ago and the Doctor said that I didn't have nothing bad in my head, that it might be migraine, so they gave me some pills to make the pain go away, but they dom't help me at all

amd I just feel really dizzy!! Can someone PLEASE tell me what its that I have?? :'/
