"I have Adhesive Arachnoiditis which causes constant severe pain. I had been on many different medications including Oxy. I asked my dr to find a medication that would help with the pain and Most importantly NOT give me the "high" sensation. Nucynta 250 ER and Nucynta IR 50mg for break through pain has work wonders!! It doesn't eliminate my pain but it keeps it at a tolerable level. I have very few side effects. The most noticeable is breaking out in sweats. For no specific reason I will start sweating profusely while in an air conditioned environment.  Other than that I get a little drowsy sometimes. Nucynta has been a life saver!!"
