I have been getting ridiculous headaches every day, what's the deal?

For the past 5 days or so I’ve been getting really horrible headaches (the pain is really sharp). They start right in between my eyebrows (almost where my nose starts) and spread to my whole forehead area. Then I get really bad pain where my temples are. Sometimes light really bothers me (if it’s bright enough) and sound as well. It usually starts mid-day to evening, lasting for a few hours. Sometimes it’ll fade for twenty minutes and then come back.

What’s going on?
