yes you know your stuff. The vein doctor I was using said you are fine and need no care. However, taking my extreme pain from the toes to the knees on both legs and with the inability to sleep because of this I went to a cardiologist, pulmonary doctor. He saw me on Wednesday,did an ultrasound told me to be back the very next day Thursday fasting. Put me to sleep and I woke up with three stents one on my right side and two on my left side (common iliac veins).The left side was so bad it required two stents. I will be returning soon for more workups. Now this is a doctor. I have been given paperwork on this. One to keep on my person and one for my records, Also a lenghty conversation explaining all of the necessities involved.
