question: My feet tops and ankles have been incredible swollen for the past four days. Swelling reduces with feet elevated but returns almost immediately when I get back up. Standing is both painful and making me nauseous. Having some trouble breathing but thinking this might be panic. On the day swelling started it was accompanied by severe left calf pain which has since subsided, but felt like someone had taken a muscle biopsy out of the back of my calf.
