I noticed a couple days ago that I felt like I had a cut or a scratch in this area when I wiped after using the bathroom. No other itchiness, discomfit or discharge at all. Then today I go and there is a bit of blood when I wiped so I had my husband take a look. It looks like a big fat pimple that I might had rubbed too hard and it busted. Nothing else... should this be a concern? It's hidden behind some fleshy folds so weird place... is this an infection?
