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.
That article I posted a link to on the BB website has skin tags as one of the symptoms. Not all roids are painful so I would be guessing it was probably just a small one that hasn't bothered you until recently and not really a skin tag at all.
