I have a protruding vein directly under my right eye that has become painful. What treatment would you recommend?

4 days ago I was taking my makeup off and directly under my right eye felt bruised almost. When I looked in the mirror closer I noticed that there is a small blue vein that was unusually visible. 2 days ago blinking started getting irritating. I looked again and this time it appeared the vein was swollen. Today the vein is more prominent and my latter vision is blurry and the right eye has started producing white "eye gunk". I have a history with spider veins other places from pregnancy.
