Some time ago I developed a problem with one of my knees, not sure how.
When lowering myself straight down, bending my knees, one knee makes awful crackling noises, but does not hurt. This also happens with that knee when I crawl on my knees.
Again, there is no pain, but I fear that this may eventually turn into something.
Any ideas on what this is and the best way to deal with it? I'd appreciate some advice. Thanks!
