    Light Blue Lines on Sides of Upper Thighs

    This morning I noticed subtle but very clearly visible light blue lines on the outside of my outer thigh, high up near my hips and going down to mid-thigh. They have a general appearance of veins, but they are very wide (thick as a pencil) compared to arm veins and they are a light blue. I was surprised to see them, and they are visible despite my tan.

    With all the new biking I've been doing am I developing newer bigger blood passages? Anybody else notice anything remotely similar?

    Yes, that possible, remember that blood is blue when it's returning to the heart. Only when exposed to oxygen (normally from the lungs or when you're bleeding) does it turn red.

    Really skinny blue lines would probably be varicose veins.

    No, it's not. Blood is always red: bright red when oxygenated, dark red when not. When you give blood or have a blood test, that's deoxygenated blood from a vein. The blue color comes from those veins' proximity to the skin, the composition of their walls, and the way light is absorbed/reflected.

    Careful when riding the MUP beyond sunset.

Many people still believe those "facts".

    I always thought oxygen depleted blood was blue. Just one of those things that hovers around, and if you're never told otherwise, there's no reason not to believe it.

    Replace `never told otherwise` with `scientifically illiterate` and `it` with ` in god/religion` and you`ve pretty well nailed Amercia. Sorry for going OT. Give me a moment to put on my flame-retardant clothing.

    Ever cut or scrape yourself? The blood you see is always red...do you believe your eyes?

    Not if someone on the Internet reports that he read somewhere else on the Internet that someone said something else.

    If you're worried about blue lines on your legs, maybe you should see a healthcare practiitioner.

    Oh yeah ... varicose veins. You might want to have them checked.

    Well, here's what I was always told:

    When you get a cut, the blood makes contact with the oxygen in the air, absorbing some of it and thus turning it red. Voila

    I guess some people will never be blue blooded

    I have ridden with people that had very prominent veins on their legs. I'm wondering if the OP had just not really noticed theirs before? Doesn't seem like a condition that could develop in a short period.

    Not true. It was all caused by that blue Sharpie you forgot to take out of your pocket before that last ride.

    Those blue lines on your legs are called Varicose Veins. Have a Doctor look at them.

    Sangre Azul -- You're now a "blue blood", part of the cycling nobility! "Blue Blooded" is also used to mean "elitist, snobish", so your non-cycling friends might think that you're an elitist bicycle snob.
