I was referred to a cardiologist for tired legs. I had a doppler and ultrasound on my legs. I have "reflux" in my veins so my Dr. is doing "ClosureFast". Has anyone had this done. I'm a bit nervous about it. So far my only symptom is tired legs and a very thin spider vein that I've had since I was younger (I'm 55) so I'm wondering if this is necessary.
