Can you advise on concerns about secondary lymphedema from EVLT & phlebectomy?

I have studied this surgery for over a year and a half... And although i want to remove bad veins i also have heard the risks if this surgery are pretty big. Mostly permanent nerve damage and also secondary lymphedema! For which there is nothing they can do. The problem is i hear varicose veins come back most of the time so really these surgeries only a temporary fix. I can't see that being worth the risk?
