If, as you say, this is happening all the time then it is not good for you. Persistant clicking is usually a sign of ligament damage or laxity and that the bones are beginning to rub together. This may lead to further degeneration, stiffness and arthritis. If problem persists then I suggest you seek medical advice.
My knees and ankles have clicked for years I havent suffered any real deteriation in my joints because of it but my knees did become painfull about five years ago my doctor prescribed Voltarol which cured the pain but gave me Diarrorea (the sh**s) so bad I had blisters on my bum so I now take Glucosamine Sulphate which renews the Cartilageous joints . My joints still click but they don't hurt now
and when you crack your knuckles, it's the synovial fluid exploding, apparently [or the air inbetween] harmless? anyway i got arthritis kicking in [BYTCH!] and i haven't had any joint clicking. also the arthritis is related to barometric pressure.
Years ago I wrecked the ligaments of my right ankle. Now when I walk after a long rest eg in the morning it sounds like Carmen Mirandas castanets. I find that if you take glucosamine (tablets, quite expensive, available in eg Boots) it helps sore/damaged joints no end.
