I have a strange bump on my pinky. Images of it can be seen here:

The bump is somewhat strange. It's a raised area of my finger, which holds two red pockets, separated by a white divider. At the time, I was in the country of Colombia when I first noticed it, about six weeks ago. I don't know what might have caused it. Initially thought it might *possibly* be some sort of blood blister, and, once the skin broke (after a couple of weeks), I started applying aloe vera to it regularly, but that doesn't seem to have had an effect. Overall, it hasn't really changed much since I first noticed it. It used to hurt a little bit to put pressure on it, but not anymore.
Does anyone know what it might be?
