Yeah, I've got one on my left nadger. Maybe 1.5 mil in diameter, a little raised. Like a tiny reddish/purple spot. Appeared years ago and has never caused me an issue. My GP did take a look some time back and was not concerned. Doesn't trouble me at all.
Obviously catching/nicking such a thing is going to cause some bloodworks (as it's basically a blood vessel that's sort of 'popped up/formed' through the surface afaik). Fortunately, the location of mine is well protected!
