Hideous varicose vein legs

CSARdiver

The upside is that this is normally only cosmetic and poses no health risk. There are a few approved cosmetic procedures you can research. I would steer clear of sclerotherapy on larger veins as the risk is dramatically increased. I used to manage the safety profile on one of the first products (polidocanol) and found far too many doctors using this off-label with horrible adverse effects. Used per the label on small spider veins < 1mm it was wonderful and minimized the scarring effect.

This is primarily genetic, but certain activities can aggravate it.
