So this is my first pregnancy and I just hit my 3rd trimester. And now noticed after a full day's work my legs are swelling. I'm a Physical Therapist and am up ALL day on my legs. Trying to stay hydrated. And today just went to a uniform store and bought compression knee high socks 12-14mmHg. Anyone else have any luck with these? Any one else, PTs, nurses, anyone who works on their feet all day have any advice? I just have no oppertunity to put my feet up other than lunch...
