Corn on toe now its starting to burn for some reason i had it for a min now..

Could be a nerve : It might be unrelated to the corn but you may have a neuroma.

Pinch nerve: A "corn" is thick skin that your body makes to prevent your shoe pressure from causing a blister. The nerve to the toe typically runs under the corn, and with continued pressure from the shoe this nerve starts to get impinged, bruised and therefore start to cause burning pain.

See a podiatrist: Who can remove the corn and off you a permenant solution if it is a recurring corn. Be very careful if you attempt to use over the counter acids, i think they can be dangerous. You can try filing the corn yourself with an emory board.
