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?
