Why do I get swollen feet when I dont have heart or kidney problenns, I retain flulds too, can nneds do that and should I drink less and eat less salt?

Lymphoedema. Do you exercise, are you sedentary or carrying too much.
lymph swelling can result from lack of exercise or sitting for too long, as can varicose veins.
this condition can also be due to hormonal imbalance, too much progesterone etc.
