Compression socks squeeze the symptom. They don't move fluid out of your body. The second you take them off, the swelling comes back.
Diuretics dehydrate you. They flush water out aggressively, but they also strip your body of potassium, magnesium, and minerals you actually need. Many women are scared of long-term kidney effects, which is fair.
Elevating your legs, drinking more water, cutting salt? Helpful. But temporary. None of them touch the actual reason fluid gets stuck.
That's the gap Nutrivena fills.
