I'm worried because my legs often swell.

Because I don't work, I don't stand or sit for long periods.

I tend to exercise a lot instead.

I go hiking a lot and walk a lot too.

Maybe because of that, my legs tend to swell frequently in the evening.

In the morning, the swelling goes down, but since it swells frequently, I get a bit worried.

There are no separate swollen blood vessels or any particularly noticeable areas.

I'm worried because it swells frequently, but this isn't like an early symptom of varicose veins, is it?
