Plantars wart or corn?!

Plantars wart or corn?

Any good suggestions for distinguishing between a plantars wart and a corn? Any good websites? I have SOMETHING on the side-edge of my big toe. It seems as though it may be a corn or a plantars wart, but I don't know which one. I've had it for a few years now and I really want to get rid of it. First I need to know exactly what it is though.

The warts have the appearance of thick, scaly skin. They can occur as small, single warts or can cluster into large areas. These clustered warts are called mosaic warts. They often resemble plantar calluses. A simple way to tell the difference between a wart and a callous is to squeeze the lesion between your fingers in a pinching fashion. If this is painful, it is likely that the lesion is a wart. A callous is generally not painful with this maneuver but is tender with direct pressure by pressing directly on the lesion. Othe lesions on the bottom of the foot that are often confused with plantars warts are porokeratoses and inclusion cysts.
I have had several of them. I like to walk around barefoot. They are really painful and feel like you are stepping on a stone. I had them surgically removed and had a very hard time walking afterward. Best thing is try a corn remover from the pharmacy. And you could try a planter's wart remover.
