I had surgery on c 5-6 a little over a year although it cured the problems I had I have new neck pain. I have pain in my neck which then runs down my right shoulder it gets to be so painful that I could cry. When it's that bad I take 4 500mg just to get the to ease up. I take trazadone and tizanadine just so I can sleep at night but still wake up with pain. I am experiencing a sharp tingling pain on my right side and down my arm when I move my neck in any direction. Should I be concerned?
