I had a little bump on my left index finger. I didn't think much of it, so I cut it off this weekend. My mom asked what I was doing and I told her. She said it was probobly a wart. Now I see another bump on the bottom side of the same finger. WTF? So now I'm using DuoFilm to get rid of it. What the heck even causes a wart? I'm so frustrated with this.
