Usually they aren't very serious, but 4 years ago I jammed it while falling down and I fractured
it. The pinky side of the joint
was protruding a little, but the doctor said all I needed was a splint.
I'm afraid that my finger's weak from getting injured so much and that it may not have healed properly after that injury 4 years ago. I also play badminton about 3 hours a day/5 days a week and I write using this finger, so I have doubts about how much rest my finger is getting.
