Pearl Belly Button Rings Weird Mark Around Belly Button Piercing? Anyone Know?

Weird mark around Belly Button Piercing? Anyone Know? - pearl belly button rings

I have my navel pierced 2 years break in March of this year. A few months ago I received a strange brand ... In real terms between the ball into the top ring navel and navel, so that the skin between the two spheres of the channel catfish. Anyway, looks like a very small dent on the size of a small pearl. It does not hurt or irritate me at all, the only .. there. Sometimes it seems that they are naked ...
It is so frusterating, I tried to take another catfish thoughts can irritate the skin of money, but has not disappeared. Has anyone this? Who knows how or what can I do?
THANK YOU SO MUCH ...
