Watching neck pain from TV. What to do?

I played Playstation with a buddy for a few hours today. To do this, we pushed my sofa a little closer to the TV. Since my TV is hanging on the wall, we had to look up constantly. After that I had real neck pain and couldn't move my head. Do you know why and what you can do about the pain?

Don't play that much

Exercise and build muscles in the neck. Take breaks and look down.

You are tense. Next time not so close. Isn't the best attitude.

Warmth could help against the pain. Massaging is also good, but it may be a little harder on its own.

Massage your neck!

Clearly, you must have had a stiff neck
there. This is the most harmful thing you can do.

You have your cervical disc on one side
stressed and thus a narrowing of the spinous processes
prooduziert.
Now you can only make a counter movement forward
try and lie on your back and rest
give.
Or give to doctor immediately, maybe he can give you
help with a syringe.
There's no quick fix or miracle.
