Please HELP! I'm in a lot of pain right now...?

I went through the exact same thing your having. Turns out having sharp pain is a good thing, if you feel an intense pressure that's when you have to worry. you might have accidently sprain a muscle. I couldn't turn my neck for 2 weeks. Try putting heat and ice on it. Switch between the two. And try moving your neck around.... even if it hurts. If it doesn't get better within the next 2 weeks you might have done some serious damage try going to the doctor and getting an xray. You should be okay though :) good luck and hope this helps!
