Tucking pinky is how I injured my ring finger.
The pain was at the bottom of my ring finger, where it joins the hand/palm. The pain/soreness lasted for over two years! My ring finger is better now, though I can still feel discomfort once in a while. Guess tucking pinky isn’t for everyone, so if it’s hurting, it’s best to stop to prevent any long-term damage.
Good luck!
