What Causes Pain In The Throat Post Whiplash?

I was in a car accident a few months ago and had wiplash and had been seeing a chiropractor to realign my neck. I popped my neck forward again today and now I have a very painful, strange sensation of my adams apple crunching and scratching the back of my throat. I had been swallowing lots of mucus because the popping in my neck seemed to open up my sinuses. Should I go to the hospital? My throat is beginning to hurt and I can feel something moving in my throat.
