Hey guys,
I'm 20 year old guy. 2 weeks ago I started having a strange feeling whenever I played video games for an hour or long in my bed resting my head on the wall and neck on pillow, actually i am mostly staying in this position. After the strange feeling appears it stays for the rest of the day. And when this happens, if i even apply a small pressure on the back of my head the feeling gets worse, i sometimes get little nauseated if the pressure applied is too much. The first day i couldn't sleep well because of the strange feeling on the and i couldn't rest my head on the pillow. I went to the hospital to check my eyes (i have myopia on right eye), sinus (i had infection) and CT scan, the doctor told me that there is nothing wrong with me and they don't think that the problem is with the eyes sinus or brain(i wonder).

Now, few days later i have the same problem which started after i played a game but this time in a table like normal people use computer. I had flu fever for the days i didn't notice this, as soon as I got rid of flu i started feeling it. The feeling never ceases, however it gets minimized once i take a good rest. I am even wearing glasses for the myopia although i put it on only when i use computer. Also, when i move my neck sometimes i hear the bone cracking with a single small "tick" sound on the base of the neck, and also when i swallow i can hear crackling in the neck. I stopped staying in that position already. I usually sleep on my sides and read or use laptop in the bed sleeping side-wise and it still triggers that feeling but not as intense as playing video game.

I am really worried. Has anyone here experienced this? I searched the whole internet for days and i still couldn't find similar posts.
