If your pain gets worse as the day wears on, as mine does, and the more you do re computers and sitting, the worse it gets, it may be muscle spasms. I find that muscle relaxants work better for me than pain relievers; however, I tried three or four until I found one that worked for me (Flexeril). And I read somewhere (will try to find it) that someone wore a posture brace at work, and that he felt like crying because it was a great help in preventing the pain from even starting.
I am not trying to say that your problem is in your muscles...I am trying to say that your neck problems may be causing muscle spasms and that there are things you can do to relieve muscle spasms.
Edited to add the website where the person posted about the brace and how it worked for him:
