I was scratching my third toe on left foot when I felt a stinging sensation that really hurt bad, and than the toe started to turn purple underneath between the top joint bones. Is it possible to break a toe that way, or could of stumped it against something the day before not remembering, and than pushing on it caused the injury possibly? Clue less what this could be but it hurts pretty bad. It's not hurting now but off and on it does this since, and turns purple.
