This means you are piercing your navel .. navel is the phrase for the area above the actual belly button** ( **other wise known as the umbilical knot)
You can't "do" anything, this "knot" is part of the umbilical cord, which is attached to your belly button, it is perfectly normal and should be there, but, if this "knot" continues to cause pain you should seek medical attention as this could lead to a hernia, very common and easy to sort out Hope this helps:)
