What Causes Headache Followed By Back Ache?

Im 6'0". 150lbs. 19 Years old. No major medical history to speak of. I have had a headache for 3 days now, it started off somewhat small the first day, gradually growing with no other symptoms but a back ache. The next day it got to the point where is was just a throbbing headache and I didnt want to move. I never get headaches, expecially for this many days when I very rarely do get one, this is a first. Today is somewhat better, but its still there, I just want it gone as soon as possible. Any tips to get rid of it other than just taking pain medication?
