Are there any hospitals in Gangwon Province that specialize in treating varicose veins?

My legs hurt a lot these days.

My legs tend to swell after I walk diligently for dieting.

At some point, I started experiencing frequent muscle cramps and my calves became swollen and hard, which has been difficult.

They say a few blood vessels have protruded in my calf.

If the blood vessels protrude, I wonder if it's deep vein thrombosis.

They say I should go to the hospital to confirm if I am the person who had the hyaluronidectomy surgery.

I am curious about where the best hospitals for treating varicose veins are in Gangwon Province.
