I have a small persistant sore on my back, thought it was a spot but don t normally suffer from them, then thought it could be a mole. It is quite itchy, dries up but then if I scratch it, it is quite painful and doesn t heal. I am 49 years old and have red hair and fair skin that has been exposed to world travel but not constant sunbathing as I dislike lying in the sun. Did have a brief affair with the sunbed however, years ago, am I now paying the price for my stupidity? Please help, Milenka
