woody edema
the tops of my feet started to look really terrible when I was at my fattest, its calmed down after losing 130ish lbs.
Nothing like OP's pic but maybe if I kept gaining weight and stayed idle for a few more years, assuming I lived that long, it would likely be similar.
I've since gained back a bit of weight but its no where near where it was, I think because I'm a bit more active and wear compression socks + shower more. man I wish I could control my appetite and didn't have so much anxiety about going outside. pic related is what it was like for me.
