I'm about 12 weeks post op after a THR. My feet and legs still swell during the day. It goes down a bit after a night's sleep, but starts again as soon as I get up. I've used the compression socks that the doctor ordered, but they don't help much. I'm scheduled for the other hip to be replaced next month and I'm worried that the swelling will get worse. Is it related to the surgery after 12 weeks, or should I try to find another reason for the swelling?
