Vulvar varicosities

I have vulvar varicose veins that bother me I’m 38 weeks pregnant at the moment. They started show up up a few weeks ago. The dr doesn’t show to much concern about them but they look really bad and they said there is a possibility they could burst during vaginal delivery. Has anyone else had them? Is there anything I can do to help them not be so bad? Are they gonna have me have a c section on the chance they could burst? Will they go away after I give birth? I’m so worried about it and they feel uncomfortable.
