Lately blue veins started appearing on my girlfriend's legs. She is 21 years old, she works in a flowers factory where she has to stand for around 8 hours on same spot and boxing flowers or whatever.
The blue veins started appearing once she started working, she is stressed most of time, her body always tired from standing. It even increased once she moved from a country to another after vacation.. Oh also she has compression socks and pantyhose if that's what it is called.
What I would like to know, is this normal for a 21 years old female? Could it be by birth? Is it work? or just being stressed can cause this?
