Or, why can’t I keep my knee bent for longer than 5 minutes straight without it going stiff.
Last week I went on a hike and my right knee, one that has had problems for a decade or so now, was giving me fits, so I favored my left knee on the downhill of the Delicate Arch hike in Arches National Park. Lefty was a touch sore but slept and it was fine.
Fast forward a week, and I fell asleep in my chair, knees bent, and now my left knee gets super stiff when it’s bent for a few minutes at a time and won’t loosen up until I force it straight and it pops. It’s been getting better these past couple of days, but why is this happening? Webmd says cancer.
