What are the benefits of injecting sclerosing agent into varicose veins?

The advantage is that you can leave the hospital soon without surgery. I made it half a month ago, and I will leave the next day. I am required to walk for at least half an hour every day. But whether it can be treated by injecting sclerosing agent can only be determined after the doctor's diagnosis. At that time, a vein image was made, as if to determine whether the main vein was unobstructed and normal.
