Too many carbs and too much sodium causes me to gain two pounds overnight which means having to restrict both the next day. I am also managing HBP and am on a blood thinner for life due to three separate instances of blood clots in both legs. For the past six months THR surgery has been front and center. I still experience swelling on occasion but it might be due to post thrombotic syndrome. All we can do is take one day at a time.
