Ok under my pinky toe not on it I have a bump on it and it hurts when I put pressure on it what is it & how can I make it go away help?

Plantar wart likely. At your age most likely it is a plantar wart or a callus buildup but you need to be sure you don't have a forgein body stuck in your toe. Check with your family doctor or podiatrist.
This is difficult. To asess by descrition and in person would be easily diagnosed. But, based on description you can have a wart, or a corn. Due to the fact we can't see it, i would recommend you see a podiatrist who will have a diagnosis for you upon seeing it.
Wart, corn ,cyst. Hard to tell without examining, but these are some possibilities in addition to foreign body reaction if you stepped on something.
