I am not happy about it either. On my left leg i have always had a vein about an inch long that has been quite dark and visible but never so much so that it bothered me or anyone else noticed it.
However now it looks worse, it isn't sticking out but it just seems more noticable. My mom said it's cos i spend so long on the compouter with my legs crossed
Also the other veins in my lehs look more noticable now.......what can i do ??
