Just to give an idea, last time I was stung, it was on the outer part of my foot. Within a couple hours, that part of my foot was as large as the inner part, and my little toe (and I have a very small little toe about one inch, basically so small as to be of no use at all) has swollen to the size of my middle toe, and remained that way for a few days.
Do big little toes have uses?
I imagine they have more uses than mine. I think mine are, more or less, at the top end of human evolution, as they have literally worn down to almost nothing.
