Are there any good procedures for reducing lower body swelling?

Hello

It’s not just my overall weight, but I’m worried because the swelling and fat are too concentrated in my lower body.

My feet swell so much that the shoes I wear in the morning feel tight by evening. Also, the saddlebags on the sides of my thighs stick out, so the lines of my pants don't look pretty at all.

Thinking it might be a blood circulation issue, I tried foot baths and massaging with a foam roller, but the relief was only temporary and didn't really refine my body lines. I am wondering what kind of treatments or injections at a dermatology clinic or body contouring clinic would be effective for this kind of lower body swelling or fat in specific areas.
