see picture. initially it was a tiny Mark, the size of a pinhead - see the other brown mark a little further away, it looked like that. I thought it was dirt, tried to scrub it off in the shower. It doesn’t itch, is dry, and isn’t weeping or anything - it doesn’t look infected. However it feels raised, as if there’s something in it, like a spot. A couple of days ago the area around it bled very slightly (I’m assuming because I’d irritated it) and ever since it has looked like this. Red area around it isn’t increasing in size and it doesn’t hurt or bother me day to day but it just doesn’t look right to me. I’ve been putting sudocreme on it.
I’m scared to go to the GP in case they say it’s cancer or something, am aware that’s probably irrational but it’s a genuine fear 
and also I’d feel stupid and like I was wasting time if they took one look at it and said it was just a weird looking spot or something!
