I was doing my usual routine of pistol squats (which I’ve been at for 4 years now, so no sudden change in routine), but then my left knee started suddenly creaking with every rep. The creak isn’t accompanied by any pain (at the moment). The creak happens when the knee is at about a quarter squat position.
It sounds pretty bad. I’m 24, so maybe this is the start of some serious arthritis?
Anyway, should I be worried? Is this going to be the start of some serious problems? What can I do to make the creak go away?
