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:)
A hernia
Yes it is a knot, as the placenta is tied to the belly button.
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)
hurna
Umbilical Knot 'Navel' is more common The "Navel" is the area around the "belly button"
Do you mean "knot"? And, what on earth are you talking about!?
Umbilical knot
I don't know what you mean by "undo" your belly button but you can get what is called an "umbillical hernia" inside near your belly button.
A navel is the area around the "belly button" otherwise known as the "umbilical knot". When people refer to a "belly button" piercing they are actually referring to a "navel" piercing.
Sounds like a herniated belly button. You should have that seen about.
The belly button is the remainder of your umbilical cord (which attaches you to your mother inside her womb). At birth, the doctor will clamp & cut the umbilical cord, then knot it & tuck it so that it heals there.
No. Umbilical cords are clamped closed and then cut a few inches from the "navel" attachment point. Over several days, the clamped cord drys up and then falls off. Where or how the "knot is tied" has no impact on the shape of the scar left behind that we call a navel or "belly button". Body size, growth during this period and later, and good ol' genetics does the rest.
