Hi @Dh5Wy83, most people mean well but don't always get everything right. I can understand someone doing an ultrasound asking if your scar related to a tummy tuck especially if they can't see your entire body or chest. They don't know what they don't know.
Perhaps they could have asked what they scar related to instead. Maybe they could have said nothing. It is possible perhaps that they were trying to understand the scar tissue and what it was from so they could report properly for your ultrasound report.
Our scars are sensitive to us and they tell our story. I have so many scars from various surgeries you could play snakes and ladders on my body. I don't worry about the comments anymore but it took me all my years to date to get to that point.
Best thing to do when people are inappropriate is to be as nice as possible and explain politely and they will hopefully learn something from you.
