Ok, so i have a bump on my lip that's been here for roughly a week and a half. It's kind of hard to see but it looks like this -- 

I will admit, I did pick at it when it was smaller. But i do think it may be infected with something, being that the scab on top is discolored. Any help with this possible diagnosis would be appreciated. 

P.S: I have another bump on the inside of my mouth on my lip, but it's small and it isn't irritated at all.
