How Can Neck Pain Caused By Straining Be Treated?

I was laying on my stomach asleep earlier this morning, my alarm went off & I lifted my head, turned to see my alarm clock that was completely behind me, so I strained to twist myself enough to see the clock, & felt/heard almost like a crunch in my neck. immediately after I was in excruciating pain and couldn't move without feeling the pain. It has been about 2 and a half hours and I am still in quite a bit of pain. It is on my back right side of my neck and the pain goes up behind my right ear. What caused this & should I go in to see a dr.? If so, what type of dr?
