I have one on my little toe. It is sore as ****! What do I do about it?

podiatrist. its the only answer

MTFU?

Corn removal pads from Boots or such like have salicylic acid in them and will deal with smaller corns. At worst, the pad will allow a little pain relief. If that doesn’t work after a pack or two, then its some liquid nitrogen to freeze it off at the local docs/podiatrist.

Or those removal pads.
