Hi Steven, and welcome to the board.
My neck cracks all the time, too. I get both a cartilege sounding cracking, which I don't even think twice about, and a loud bone-shifting kind of crack when I tilt my head to the left just so. If I don't make it crack periodically, ie, a multitude of times everyday, it gets so it doesn't want to crack and I get a terrible headache that lasts for several days until I can pop it back with a hand-held neck massager, running it down the side of my neck at just the right angle. Sounds weird, but that's the way it's been for years. For me, I think it's related to my many other back issues. Is this a new thing for you?
I suggest that you try to be very aware of your posture at the computer. Get up and move around for a couple of minutes every 1/2 hour or so. If you have a laptop, maybe you can find a shelf that's about eye level that you can move your laptop to sometimes so you can stand in front of it and change the stress on your neck. Move it back and forth between a desk and the shelf.
If it persists, you might want to see your family doctor just to be sure it's nothing serious. If he's concerned, he'll refer you to a specialist.
If you don't get a response on this board that seems to fit for you, you might want to try the spinal disorders board. There are more people over there with cervical issues than on this board.
I wish you the best!
