I would be more concerned that they are popping into what she thinks is a skin tag that she has had all her life. hemoroids are one thing but I would be chatting to your Ob/GP or middy about it first.
It's also possible it's a boil. I have a skin tag at my lower butt cheek right near the crack and it got inflamed a while back. Because that is such a sensitive area I suggest getting it checked hun
