Why is my right eyeball sinking in its socket and drooping lower than the other? (Photo)

I had gotten a pinch in my shoulder and one day while turning my head a little forcefully the right eye immediately went lower and into its socket. I have also noticed turning my head to the left it appears worse. I also feel it pull i guess would be the best way to describe it , pulling down in my neck and like between shoulder and spine tilting my head in certain ways also make it worse. When I lie down on left side I also feel as if though it pulls deeper inside. The whole side pulls backdown
