Varicose veins are...

Are you talking about a paper-like tendon protruding?

My tendons haven't protruded, but I sometimes feel numb and sore.

My calves don't protrude, but on difficult days, my instep hurts and swells up.

The back of my hand also becomes prominent in the evening, but I don't pay much attention to it.

Could this also be varicose veins?
