Serious Headache

About 2 weeks ago I started getting headaches and I noticed I was getting them every day. For Starters, I am a graphic artist, I work in front of a computer all day and sometimes at home. When I got the first headache I noticed that I'd be concentrating and I get a dizzy spell, like someone just lightly grabbed my head and slowly moved it in a circle, not unlike vertigo. The headaches started afterwards. My Eyes have been getting tired as well. After a few days I had some headaches bad in the morning. No troubles sleeping though. I've noticed a really sore neck and I'm having to crack and pop it myself. But the headaches are now focusing in on the left side of my head and come out of nowhere and are like brain freezes, very sharp sudden and linger and then slowly fade. I get them several times a day. I've always been sensitive to light so I wear sunglasses all the time. I went to the doctor and had an MRI done today, but I can't wait for results. It's like taking any test and not knowing the result cause you didn't study.

Any suggestions of what it might be could help me at least relax.
