Pinkie/Pinky Finger getting fat and tingling feeling.? - pinky pics

Soo, a month ago was my left little finger to a lil more fat (below) have received and this tingling sensation from time to time. It does not hurt or stop responding. I do not feel any lumps that will not only get larger. I do not know why this is happening and how I can stop him. Thank you! : D

I have pictures if you want to see.
