My neck is really out of place, methods for fixing?

So I tweaked my neck during long time activity, and what I think is the C7 is wayy to the side (tilted at some times, and to the left when my necks bent, and sometimes to the right). And this morning I woke up and now I cant turn my head more than 40 degrees to the left, right, or down. Can anybody give me a solution to how my friend could try and pull everything together? Thanks.

Also if it helps, it's the biggest vertebra that's out of orientation, and the one below it hurts when i push on it.
