I felt it yesterday in the shower - it's a rough texture. Its on the back of my shoulder in a hard, but not impossible, to reach position and not somewhere I can easily see either.
DH "can't remember" if it was there before and I cant be sure either. I do have fair few moles but this is a biggie (a 1p coin would cover it but only just).
Anyone dermatologists here?... does it look like something to be concerned about?
