I'm curious about varicose vein treatment.

I was diagnosed with varicose veins around the time COVID started, but I didn't find it very uncomfortable, so I just left it alone. Recently, however, I sometimes get cramps in my calves when I stand for a long time or overexert myself. Could this also be related to varicose veins? I am currently wearing compression stockings and elevating my legs while sleeping. If treatment is necessary, I am wondering if there is a risk of recurrence.
