I just discovered these blue veins on the back of my legs, behind the knees. I showed my friend and she says that it's not healthy. She thinks it has to do with poor blood circulation.

Is that true? Am I the only one that has these? Are they a bad sign?

Btw: The veins kind of bulge out of skin just enough that you can feel it when you rub your finger over it.

It's a little hard to see it in the photo I provided. As it does no justice, lol.

Please don't mind my bright white leg lol!! I don't tan on my legs very well..but everywhere else I do. LOL. 😁
