It's varicose veins.

I had a protruding vein in my calf and went to the hospital for treatment. I think it was about five years ago.

At that time, he said the varicose veins weren't severe, but they were present. When his legs feel a bit heavy, he manages by wearing medical compression stockings and elevating his legs a little, but there's no pain or significant discomfort.

I'm curious about what symptoms occur when varicose veins worsen. Do the legs feel numb or painful?
