| which supplement for a knee "crack"?
every time i squat down my right knee makes a wierd cracking sound. it doesn't hurt, just feels a bit wierd when i happens and makes that sound. firstly is it a problem at all? could it be the first sign of something to worry about? even if it isn't, what would people recommend to get rid of it? i have glucosamine or MSM in my head but i'm not really sure whats causing it so i dunno what to do about it?
