Well, I don't think I've ever had a mole before this. It's not a pimple or a cyst. It's raised above the skin and it was dark brown before the top came off. Now it's the usual freckle-coloured brown and still a little raised. It didn't bleed when the top came off. I've never had anything like it before.
It's now only three weeks and a few days til I get home. I think I'm going to wait to see a GP, rather than paying US$50 here to see a doctor who may not really know much about skin cancer things. I'll get the obst to look at it again too and his nurse, just in case. (My insurance covers the obst visits but not regular GP appointments.)
Thanks for your replies.
