Hi Go slow I suffer with post run tenderness in both knees, particularly going up stairs or walking more than a couple of miles. I find it helpfull to run one day and rest the next, two days running consequatively causes much hurt! Have also just started taking Condroitin & glucosamine complex gels (extra strength!) as recommended by my chiropractor (very pricey!) but may take a few months probably to see benefits, it allegedly helps repair joints & lubricate etc. Will let you know if it works. But I,m definatetly going to give M's carrier bag excercises a go.
