What is the black stuff lining in my belly button?

Question

The interior of my belly button has some blackish brown hard stuff that's attached to the skin. What is it and what is it made out of?

PS.It's Not navel lint!

Answer 1

Could it be a scab?

I'm not sure. Try putting a little rubbing alcohol on a Q-tip and clean your belly button out to see if it comes out... It sounds like hardened dirt or something.

Answer 2

is your belly button pierced?

if so wash it. it's probably infected
