Re: Pressure at back of head that gets worse looking at lcd screen.
I have a very similar feeling to what you describe, and unfortunately it's been there for about 6-7 months. On a bad day, it may radiate up through the side of my head too. I went to a headache institute, who suggested some kind of neck trauma and I went through physical therapy. Unfortunately I don't think that was the complete answer, because I still have that feeling (although I did have days where it seemed to improve). At a new doctor I'm seeing for a second opinion, they are having me get x-rays tomorrow morning to start, to look for any kind of issues in my jaw or neck. Basically, if there is any kind of joint, ligament, or other issue, the muscles in the back of the head will try to compensate for that weakness and will ache as they support your head more than usual.
I pop my neck very often and learned how it's possible to sprain your own neck or at least weaken the ligaments enough to cause these kinds of symptoms. I have been giving it up and feel a lot of muscle spasms and more tightness, so I wouldn't be surprised if the cracking was just prolonging my healing. Of course you don't have to be a neck popper to get something like this. Slouching while looking at a screen (it caught my attention when you mentioned the screen), sleeping in a bad position, and other things can cause it as well.
I feel quite similar to how you described... it's like a lot of pressure and more of a dull ache, but it can certainly still wear me out and be somewhat disabling since it feels like a deep pain, if it gets bad enough. I feel best when laying down since the weight of my head doesn't have to be supported!
I hope with yours, it goes away on its own. You can keep an eye on it and give it some time, but if it continues, see a doctor about it. I took muscle relaxers and had no relief from them (Flexeril) and now I'm taking an anti-inflammatory used for arthritis (Mobic) but it's only been a couple of days and I don't notice relief from it yet. Have you tried any over the counter medication?
PS - I know it sounds so basic, but try to sit up very straight and keep screens at eye level and see if that helps over time. I bought computer stands to raise all screens at eye level and make sure to keep my back straight and my neck straight... often times my back would be a little bit hunched and my chin slightly forward... this can cause those muscles to get pretty tight.
