Edema at 16 weeks

Hi po, main adv sakin ng OB, if all of a sudden, nagswell both feet, hands and face is ER agad. Can be a sign of organ failure pero if feet lang naman, mag stack ng unan then elevate the feet during sleep. I was diagnosed with preeclampsia with severe features around 33weeks when my feet, hands and face swell. BEST IF YOU CAN GET IT CHECK WITH YOUR OB PA DIN.
