knuckle cracking

ok im sure this has been answered before but my internet connection is being really stupid and wont load half the pages. anyhoo is your cracking knuckles bad for you? has it always been discouraged because its not polite or does it give you arthritis?

Cecil’s response:
What’s actually cracking when you crack your knuckles?

No arthritis, slight release of pressure built up in your joints, no biggie. I do it 20 times a day at least.
