I had a freckle that I've had all my life. Then over a 2 week period it became really raised, changed colour, became itchy and sore. I went to a GP and they've referred me to a skin cancer clinic. However, since I've seen the GP it got really really itchy, so I scratched it, it bled and pussed and now it's fallen off altogether. Do I still go and see the specialist or do I cancel the appointment?
