Blood circulation, swelling

Is it because my metabolism changed as I gained weight or due to lack of exercise?

Whether it's because of a change in constitution, even in my twenties

No matter how long I walk, my legs don't swell, not even my calves.

My legs, which hadn't been active, started to feel a little after I turned in my 30s.

Even when walking, my legs swell twice as much, and my shoes become smaller.

Walking for a long time has become difficult.

Wearing compression stockings and walking without swelling, what is the problem?

Since I don't have one, I can't wear it for a lifetime, so I prefer traditional medicine.

Is complete recovery from treatment possible?

And regardless of summer or winter, the upper body stays warm.

My lower body below the waistline is always cold.

I'm not sure if they are related, but both of these.

Is there a treatment that can cure the condition?
