I have this wart , atleast i think it is on my big toe on the underleft side of my toe. this bumb is large and HURTS an unbelievable amount to walk on or touch. there is also somewhat of a covered hole on my toe also on the lump to where i can see this "black object" this object seems to be growing INSIDE my toe deeper, what is it? what to do? and is it bad if left untreated as in will it go away on its own?
