On Monday I woke with a neck pain not unlike having slept in a bad position. However, it got worse during the day and I have hardly found a comfortable position in which to sleep since. Tuesday, I had chills and stayed covered in bed until it broke after an hour or so. Advil has helped but the pain has advanced to between my shoulders and it's difficult to turn my head without hurting. Are these symptoms of something I should be checked for because I don't want to continue with the Advil very long if there is a better solution.
