Itchy bubble of liquid

I think something bit me on my toe. There is this thing (dd shaped bubble)my big one that seems tender and the entire area around it itches line crazy. Soap and water does nothing to make it stop itching. and that pink chalky stuff that says its lotion but you can’t rub it in is not working. I’d take a picture and show it to you all but I’m not about to dress up my foot so you can stare at it. (Hopefully you don’t want to see it)

I’m tempted to take the scissors from the first aid kit and cut it open, I’m sure it would scar so I’m not going to.

What could make a bump like that?

Poison Ivy? Fire Ant bite? There are lots of fire ants in the area you live.

Don’t cut it open if you don’t know what it is! Besides scaring it might spread.

I don’t know what might cause it, although fungus is a possiblity, but cortisone cream might relieve the itch.
