Hi, I Punched A Cement Wall On October 29 Of

Hi, I punched a cement wall on October 29 of this year. My hand (mostly my knuckles) got swollen for the next few days. After the swelling went down, I noticed a bump on my middle finger knuckle. When I squeeze it, I can feel a little pebble like object that could move around and it hurts bad but when I leave it alone, it doesn't hurt. But still to this day, my hand hurts to squeeze things, or move things and hurts after ive been writing a lot . its not swollen but there's been a (darkish) bump on my knuckle for the past month and a half.
