Is this a wart?

[WartOrNot]

Ds has this thing on his little finger. I think it's a wart and have used Bazuka Sub-Zero on it twice, but it's not doing anything.

Could it be something else?

Looks like a wart to me. No answers on how to fix them - I had about 30 when i was a child and we tried everything, then they just cleared up of their own accord one day, pretty much literally overnight.

Apparently that happens because the virus that causes the wart is so sneaky that your body's immune system often doesn't notice it. Once your immune system recognises that the virus is there, it attacks and swiftly gets rid of it.
