I discovered this mark around 1.5 to 2 weeks ago just above the crease on the underside of my right breast. I firstly thought it was a bruise and intermittently kept checking it but it hasn't faded or changed at all.
I think it appears to have a darker red line around the outside so I googled ringworm and thought it could be that but then I looked at it again and it's not quite as defined as the online images.
As it's not changed in nearly 2 weeks I figured I should probably make an appt with my GP. It's about the size of a 5p.
Does anyone have any suggestions on what it could be?
