If they close my veins with the treatment, where does the blood go?

This is a frequent question that arises when you do not fully understand the disease. What the treatment closes are not the veins, they are the varicose veins that are already sick and that are not doing their work, the blood they carry does not have the direction it should have, towards the heart, but instead, it has reversed the flow causing it to now go towards the feet. Therefore we close the veins that not only do not work well but in many cases, they overload (and in time they can spoil) veins that are doing their job.
