Hi, I m a 14-year-old female and have suddenly visible veins on my arms, wrists, hands, and fingers. One or a few bulge out just a little bit, but I haven t really done anything lately that I think would cause it to do that. If I raise my arms, it looks like nothing happened, but once I lay them down again, they become noticeable. I took a hot shower, and it seemed to help a bit, but I m scared more veins will start to show up (once again, only one actually protrudes). Lately, I haven t been very active, so could that be the cause? What could I do? Thank you so much.
