The technicians performing the ultra sound were very nice and helpful to answer questions. At the end of my appointment I was greeted by more staff to answer my questions. However, I still do not completely understand why my veins need to be lasered, what is getting removed and what will remain, and if this will ultimately be better for me long term. If my "defective" vein(s) is 80% functional then I would still like to keep it. Perhaps a 3D diagram showing what veins I have, which valves are non-functional, and what is getting lasered would provide more comfort.
