You can try the following:
1\ Don't sit or stand for a long time, keep the same position for half an hour to have a little exercise, or change the position.
2\ daily wear loose pants or skirts, do not increase the pressure on the skin and blood vessels in the legs.
3\Regularly do some relaxing light exercise, such as: walking / jogging, etc., to improve the body's metabolic rate.
4\Keep your legs warm, soak your feet before going to bed, and do a foot massage, do not need to be how professional, as long as the rubbing of the soles of the feet, can also play the same role!
Persevere for a while, must be able to improve! I hope you can help!
