"i have been on nucynta for 2 years following a ten - twelve foot fall. nucynta is without a doubt the best pain medication i have ever been prescribed. it works well  on my severe shoulder, back, and neck pain. without the nasty side effects of other opiates i was taking such as hydrocodone. i am able to stay alert and i have not built up a tolerance to it. nucynta has been a game changer for me. . ."
