Varicose vein surgery

I had varicose vein surgery after giving birth to my first child.

A bulging vein appeared on the upper right thigh, so I went to the hospital and was diagnosed with varicose veins; I had surgery on two veins in both calves!

Lately, my legs feel heavy, and when I sit still in the evening, I feel twitching in my legs... Could this be a recurrence?!

It's been a long time since I had surgery and regular check-ups, and I haven't had any for years!
