I've got an area on my shoulder that is very strange.
When I get angry (ffighting etc) a darkish mole appears within 48 hours but then begin to fade graduallyand will vanish once more within a week.
I've had this problem for around 3 years now. It is not itchy, not strangely large but a tad non-round but it is black and not raise.
bit scared about this but never had the courgage to check it out
