Blister? Any idea what this could be? (Pics)

My daughter has been complaining about this painful spot on her toe, at first i assumed it was a water blister since it's sort of clear looking around and inside, however it's been weeks and it's gotten slightly bigger.
She says it hurts when she walks it feels sore and bruised. I don't wanna show up at the doctor for this and waste anyone's time but at the same time I can't really stop thinking about what it could be, how long will it take to go and why has it gotten bigger?
