Man I been having a headache for two weeks and I thought it was going away and it's coming back.

Don't come here for health care advice, you need to talk to a health care professional for more and better advice.
It could be nothing but always best to have it checked out.

I had something like that in high school and they gave me some darvocet or however that pill is spelled.

You must be thinking alot of stupid things and maybe you got hangover.
