I've totally convinced myself that I have skin cancer on my lower leg. I've always suffered from eczema but this isn't like that. I noticed that there was a small discoloured patch of skin smaller than a 5p piece.  That was the other day. I noticed today that you it's now very red - it's flat but looks like there's a little hole in it. After dr Googling which I really shouldn't have done, I'm now convinced I've got squamous cancer cells. The drs aren't open at the weekend and I'm going out of my mind with worry!
