Bulging vein on areola breastfeeding

I have a small vein that sticks out almost like a little swelling on one of my aerola. It seems to get worse after nursing. It’s prob around an inch in size from the nipple to the end of aerola and only swollen protruding on the actual areola. Does anyone else have this ? It worries me. Please don’t say see a doctor Bc I was literally just at my yearly and noticed after the fact.
