Headaches??

I am 15.3 and I have had the most ridiculous headaches. I have had this one since Friday of last week...i feel it all in the back of my neck and the pressure is on my temples. Does anyone else or has anyone had this symptom? I go to the doctor next week but I'm debating on whether calling and asking before I make it in. I hope this is normal but would like to hear from y'all.
