"i have been using nubain for the last 6 years and i can honestly say, it&#039;s changed my life.  i am in dire need of a knee replacement but nobody will do the procedure due to my age..i am told by orthopedic doctors to wait until i&#039;m at least 46( i&#039;m 44) so i have 2 more years to wait.  i was a collegiate gymnast and coached for 17 years, have had 2 acl surgeries and basically have bone on bone knee pain.  i have tried everything..but this is a life changer.
