Yes. Yes. Yes.
I've been having chronic knee pain and my doctor told me I have fluid on my knee caps. They hurt when I bend, squat, climb, exercise, ecc. But after taking glucosamine for a few months my knee pain has gone away almost completely. I just have random flare ups now and again, but  that is of no conciquence when I was used to having my knees literally throb for hours every day.
