How to make my fingers' bones go to it's original size. Do I need surgery? or just massage it? (photos)

I pop my fingers' joints a long long time ago, I think I started doing it when I was in 5th or 6th grade. I only stop when I noticed that my fingers' bones becomes bigger and bony than before, it looks so ugly and I hate it. I stopped doing it when I was in 9th grade and until now. They say that when you stop cracking or popping your fingers/knuckles it will go back to it's original, but in my case it doesn't. I really want to make it look like as it is before but I don't know how.
