                        I have pvns too. I've had 3 surgeries and am not facing  a fourth. According to my doctor, doctors do not know what  to do with people with pvns. He said some try radiation but there  is no guarantee that it will work. And in my case, it is out of the  question because I've had varicose vein surgery and a knee replacement.
