Dotsie, I can take only a few things since my heart attack, but Advil is one of them. That's ibuprofin I think. I can only take 2. It is what I take for my almost constant back pain. It takes the edge off, but that is all. The one thing that does work is tylenol with codeine. Unfortnately, the doctors don't want me to get hooked so they won't give me anymore. However, for you...I would think you could take it until the knee pain is relieved. My back pain seems to be chronic and I am stalling getting an epidural injection for the past 9 months. It looks like I will have to give in soon.
