I hurt my upper back a few months ago playing around with my friend. I quickly snapped my head forward and back and in that motion I felt a popping on my upper spine right 3-4 inches down from the base of my neck. The next week my neck was very stiff but it slowly went away. The pain has recently come back giving me a stiff neck. Whenever I look down to a certain point both the back of my neck and the the same area on my spine feels pain. Any ideas on what I should do? I'm guessing I should see a doctor but wanted to get the forums thoughts.
