It is my experience that the syptoms do not jump, although trauma would cause a jump, I'm sure. After I had my first symptoms, clicking and dislocation of the jaw - it was about 4 years later when I became in constant pain. Although I have not been diagnosed with the arthritis, I believe that is what it has developed in to (due to the grinding and crunching noises). I feel that if I had taken my mouth more seriously years ago, I would not be in this mess of constant pain. Please take good care of yourself!
