"i was on vicodin 10/660mg for nearly two years when my doctor switched me to help save my liver.  it works just as well if not better.  i take 3 a day as needed for my osteoarthritis and fibromyalgia.  it doesn&#039;t take all the pain away but i am able to do daily tasks but my knees still hurt too bad to do cardio.  i also use voltaren gel on my knees, back, neck, feet, and elbows but my knee pain is too severe.  i&#039;m going to have surgery on my left knee soon and if it goes well i will get the right one done and hopefully i can start doing cardio again."
