I'm a peds nurse, so I'm not altogether uneducated, but this is.out of my field. My knees have felt swollen for at least a week ,and now they are.visibly swollen. My left elbow feels tight and there is 2-3+ pitting edema over both shins. Obviously, this isn't good but I'm not sure how worried I should be. I tried to get an appt with my doctor, but they can't see.me before Thursday. I have no shortness of breath or chest pain or cough. For now I'm working from home with my feet up, trying to decide how aggressive I need to be.about this. I have never had feet or leg.swelling.
