Hi
I'm looking for a bit of advice really. Over the last couple of days a small scar/cut/mark has appeared on my head. I don't remember catching it on anything. It hasn't bled, but is a bit tender. I was just looking for some advice of what it could be.
I'm 28 year old living in London. I'm not a fan of the sun (not that there is much in England), and rarely ever go out in it.
I've attached a photo and would appreciate any advice.
Thanks
James
