"this medication was given to me for complete knee replacementpain.  it gave me no relief from the pain, so little relief i can&#039;t even say, my therapy session would put me through the roof whether i took this med 15 mins. before or 1 hour before .  it&#039;s been a horrendous experience and i will never go thru this again, even though i need a 2nd one done. i had in home therapy and the pain was horrendous all the time, these are more like sugar pills and the drs. won&#039;t give stronger because they think you&#039;ll get addicted."
