While exercising my pinky at playing the guitar I noticed a huge problem which I am not able to find on the internet. My pinky kind of cracks when trying to bend it from its flat state. I tested it on my friends and actually many of them have the same problem. My instructions were to straighten their pinky finger and simply bend it without moving the other fingers.
Here is a video of me exercising and about in the middle of it you can see my pinky finger cracking and bending really fast.
Is there any chance/way I can overcome this syndrome?
