Hi I have had both legs done and mine were really bad. It made a massive improvement although I still have surface veins. The main advantage of the surgery is that it is day surgery and after an hour or so you can go home and are back at work and driving within a couple of days. However you need a lot of local anaesthetic injections and it can be uncomfotable though bearable. You have to wear a very tight stocking for about 10 days after but can shower etc. The first time I had it done (on my worst leg) it was quite painful for a week or so after and I bruised quite badly, the second leg was much easier. I thought they didn't do this op on NHS any more? If you are given this option over conventional surgery I would recommend it.
