(Question) My legs swell in the morning and evening. What could be the problem?

I already have a lot of worries because of my thick legs.

I have lower body obesity, so I massage my legs whenever I have time, and I don't wear compression stockings at all.

My job doesn't involve standing a lot, and I sit almost all day.

When I wake up in the morning and before I go to bed, my legs are... so thick.

I can feel it even without touching it. My legs are swollen.

So I'm giving her a massage and applying a warm compress, but I'm worried because the swelling isn't going down.

There were times when I was embarrassed and stressed because of my legs on important days;;

Why do my legs keep swelling? Does eating salty foods have an effect?

If anyone knows how to prevent leg swelling, please share!
