Varicose vein on labia?

Amanda
Has anyone noticed swollen bumps on your labia. Really hard to see bc of the big belly bump but it is purple/black on top and hurts?
They are common in third trimester. I read that there is nothing you can do about them but use ice to take away swollen area? Has anyone done anything different?
I was freaked out to find it until I read about it online. I can feel it when I walk though!
