There's no such thing as off topic in the random discussionA little off topic;
From a google search, cracking knuckles doesn’t make your knuckle larger or cause any damage to your tendon.
My fingers now?? I have tendinitis on 3 fingers and also knuckle getting larger and hurt so bad that I have to go to see the doctor today.
I really hate doctor google, they always says that you’re going to have cancer
Cracking joints on a regular basis can lead to early degeneration of the joint and potentially arthritis in the joint. This will cause the joint to become inflamed (swell up a bit) and hurt.
It's preferable to not crack your knuckles or any other joint if you can help it.
