Massage device good for leg swelling

I tend to sit for long periods, and perhaps because of that, my legs tend to swell because blood circulation doesn't flow well.

At times like that, I regularly use a calf massager to relax.

They gently massaged the calf muscles, which were knotted and rotating with four protrusions.

It also has a heating function, so it warms and relaxes you.

If I do this and sleep, I no longer experience leg cramps during the night.
