Migraine

Today I woke up with a huge headache. Thinking it would go away I did not take medication. It didn't cease all day. My head hurts more specially when I look at lights or move too fast. I thought it was because I haven't slept well but after a nap I feel the same.

I know you guys aren't doctors but I have a college scholarship interview tomorrow and I cannot go to the doctor till the weekend.

Does anyone have this ? What kind of medicine can I take?

Thank you guys in advance!
