My finger is advanced. Something's wrong with my finger (the middle on my right hand). The other day it started to get sore in the middle for some weird reason, not sure why, and now there's a huge buldge sticking out of it, and it feels like bone, I'm sure of it, it's just as hard as the rest of my finger. It's sticking out like 1/4 inch and it looks really twisted. What the hell is it?
