At what point is swelling a problem?

Erica
My blood pressure is somewhat on the higher end but not enough for my doctor to be concerned with preeclampsia. Anyone my feet are so swollen today! It's the worst so far.. At what point is this a problem? I had an appt early this morning but just had the normal swelling so didn't mention it.. Now I can barely walk👎🏻 any advice on the topic??
