Ive noticed today that I have a tiny little brown spot that looks like a freckle on my top gum. I am fairly sure it wasn't there yesterday. I suffer from anxiety and obviously am now terrified that this is the sign of a serious illness. Has anyone else had a freckle type thing on their gum? It doesn't hurt, it almost looks like a tiny cut but there is no pain when I touch it so I don't think it is.
