"i have chronic pain that wraps around the right side of my rib cage and believe it to be nerve/muscular.  i was taking tramadol for many years along with my lyrica, but the tramadol just wasn&#039;t working anymore.  my paid doc replaced the tramadol with 50 mg nucynta twice per day.  the results are phenomenal - i am basically pain free and able to function fine at work on it with no side effects of any kind.  this medicine has improved my quality of life and i can&#039;t believe how much better i feel."
