Hi, hope that someone can offer some advice.... DD saw her GP this week and she looked at her belly button and noticed it was still a bit weepy. She used silver nitrate inside it (applied with a long stick thingy) and she said that would just cauterise it. However she now has an area of staining around her belly button that is grey and about the size of an old fifty cent piece. I am not very happy and my GP said "it should fade in a few weeks"......should?!?!?!?!!?!? Has anyone else experienced this and does it fade?
