I get a severe headache every day at the exact same time. Anybody what this is? and whats the best way to deal?

For the past 5 days I have been getting a severe headache at almost exactly 9am in the morning. It starts as a dull throb always in my left temple of my forehead. then it becomes worse within a few minutes. I sleep well throughout the night and wake up to this headache. I am baffled, i havent been doing anything different in my daily routine. The headache lasts for about an hour then subsides as I lay in bed rubbing my temple and trying to sleep. Anyone know what this is? I am really worried now since its been five days. side note: I lost my job four months ago and currentyly have no health insurance so I can't really go the doctor right now.
