pain
"I am a register nurse working 12 hour shifts.  tugging pulling.  I fell back in 1998 and damaged both of my knee's severely.  I have taken many different medications to control my chronic pain.  I have been taking nucynta 75mg every 6 hours since summer 2015.  Not all of my pain is gone, but I can tolerate more activity.  My life has improved greatly.   It is great that I do not have to burn up my liver with Tylenol.  Like all medications; it is not for everybody.  It works with my body chemistry.   My pain levels are low enough where I can sleep."
