I am almost 21 years old, 5'4'' and around 190 pounds. I went to bed 2 nights ago then I woke up to notice that I could see dark blue veins all over my body (arms, legs, feet, breasts, stomach) but it's the worst below my knees. They are not raised, just very dark blue.
I am not pregnant.
I do not drink.
I have been in the 180 -190 pound range since I was 18 years old.
What do I do? What are they caused by?
