Can you go a bit more in depth? Is it pain? Is it a huge discomfort? You gotta be more specific about what you exactly feel and when, and how is it affecting you.
Personally I kinda suffer form neck issues aswell, since kid I've been on the pc and never had anything or anyone calling my attention for my posture, so now problems are arising. Big discomforts, you just want to neck and rip your neck, its not really pain, but bothers you the whole fucking day, its hugely tense, and you cannot ignore it. On very very bad days gives you headache aswell, and you cant really get better till the next day.
As someone said, I also sleep without pillow now, but I sleep on my stomach, which is not good, but can't really sleep in any other way. But I've done some research and stomach sleeping + pillow = huge burden for neck, makes neck staying with huge pressure for the whole night, you can also test this, put yourself in stomach, and feel your neck with and without pillow. Regardless you should sleep on your back, always.
Never found a doctor or massagist or anyone that really helped me with this. So I had to dig myself for a solution.
Current what has been helping me is a good chair (must have a headrest, if it doesn't dont even dare to buy it, you need it 100%), and putting my monitor way up, forcing me to rotate my head upwards instead of downwards (which is what me and probably you have been doing all these years)
With this setup I've been noticing huge improvements over time, and I've been way better than before. Used to have like a week straight of super tense and discomforted neck. Hasn't been happening anymore.
So for reference, if you want to put your monitor high up, I currently use "ErGear 13-35 inch-/12 kg-monitor holder" (and use it as high as you can), you can search and you will find it.
For chair search for ergonomic chair, and pick whatever you like the most. Tips: Make sure the one you has a movable headrest, for best positioning to fit your neck.
As
@Zwielicht said, standing desk might be really good aswell, I never tried cuz it would be hard for me to setup on my office desk, but I heard its really good aswell, hopefully I will give a try on it in the future.
If anyone has also good recommendations I'm all hears. I'd love to hear what has worked/not worked from other's experiences.
Also does anyone know any specific massage type that works only on the neck area and its muscles, and works really well? I personally never found one, but would love to know if there is anything out there that actually is worth your money.
