Quite often varicose veins do not give any subjective symptoms or patients get used to them over time.
Although they might stay unchanged for the rest of ones life they will never go away. They can be occasionally left alone, however due to progressive character of the disease, it is better not to omit new skin changes caused by varicose veins, or worsening leg swelling, which might need a treatment.
Also, smaller varicose veins heal faster with less discomfort than big ones, so it is better to consider the treatment earlier.
