I had what I thought was a pimple come up on the back of my hand about a week ago. Thought it was a strange place to get a spot but vaguely assumed it might have been an insect bite or something similar and didn't think any more of it. But it's still there, and has changed shape into a raised but flat, reddy pink spongey blob with a dark red edge and a teeny dark dot right in the centre.
I'm off to the doctors to get it checked out but has anyone got experience of this sort of thing?
