question: What could cause this re-occurring pain that I have experience on the on my right side on back of my neck ? at times it can get a little stiff as I can hear some grinding on my neck collar. In 2006 I was diagnosed with slight de-generitve arthritis on my c-5 & c-6. cervical. Due to allergeric conditions I stopped taking Celebrex about 2 months ago, and it is about the time this pain started.
