What is this and how should I treat it?

its nigger foot, hang yourself by the foot from a tree to cure it

seconded, put a bandaid on after but if you're on your feet alot wrap gauze or paper towel over the bandaid keep it on

>DON'T POP IT!
why not ? i pop that shit like crazy

Basically has higher chance of infection. Those blisters look weird tho bro. Like already infected. Which isnt good.

Eat it and post it

obviously a worm/parasite. gotta go see a doctor to get it removed

Probably a blister but it doesn't look good, go to a dermatologist if more of those appear

Looks like a plantar wart that already gone through some treatment
why you lie to us OP?

No idea what it is but you should treat it with love and respect.

Its a sandmite, it can cause necrosis! Go to a doctor.
