Varicose vein treatment methods

I walked the Jeju Olle Trail last week during my vacation.

Walking the Olle Trail has been ongoing for 10 years.

I have already completed it several times.

But this trip was very exhausting.

My calves were so tight and painful, it felt like they were going to burst.

I originally had varicose veins, and the veins were also protruding too much.

I'm worried that if it gets worse like this, treatment might be necessary.

I would like to ask how varicose veins are treated.

Please share your helpful advice if you have treatment experience.
