It seems to work in the office only on the use of the feet, because most of the time I just sit. But the lack of movement leads to poor circulation and causes varicose veins. Notice the blue markings on the legs, I went to the doctor. He wrote me a cream varicobooster and try recommended, to give, within one working day, although any physical activity the feet. I kept all of the recommendations, and after one and a half months, my leg is back to a healthy state.
