While these vulvar varicosities are sometimes painful, they are not dangerous to your pregnancy and will reduce in size after your delivery.
You should see your healthcare provider to assess if you have varicosities on your labia. If you do, you may find some relief by resting on your left side. This moves your uterus off the largest pelvic veins, and allows your varicosities to decompress temporarily. Cool compresses may also provide some relief. Lastly, ask your physician about specialized maternity supportive belts. If you use such a support, put this on first thing in the morning to relieve external pressure on the vulva. This could reduce the swelling and discomfort that occurs when you're upright.
