This thread certainly hit a nerve...or something! I am 56 soon to be 57 and over the last year I have lost about 15 lbs, started riding a bike, got a dog and so am walking said dog but now I'm experiencing sometimes excruciating knee pain! It is really irritating to me because I am not obese and I am active but this crops up all the same. I love getting out in nature riding my bike, walking my dog and hiking and so having my knees go out at this point just sucks!
i currently am wearing a knee brace and I either ice or apply heat (ice seems to be best) but it isn't going away. This us a fairly recent thing so I'm still trying to figure things out.
