I am a female, and for the past two years I ve had a strange and pretty much unexplained blue bump underneath the skin on the back of my hand. There was no obvious hole, it was just underneath the skin. It s not itchy, but it seems to have grown in size over the past year. Me being me, I was absently itching at it one day and accidentally scratched the skin off it. It seems to be leaking a watery fluid, and stings a bit. It was worrying because the blue grey more blackish in color now lump has grown slightly. I went to a doctor ages ago about it and she dismissed it as a mole underneath the skin. I just need a third opinion
