I have a terrible itch on my upper chest and only there. It itches badly to the point I wake myself up at night scratching at it. There is no visible rash there or really anything I can tell. It often becomes painful when I begin to scratch it. It's been occurring for about a week now. I don't really have any other symptoms that I know of... also the only real medical condition or whatever that I have is a benigne tumor on my liver of some sort. Thank you for your time.
