I Had Charcot Foot Collapse On Left Foot Two Years

I had Charcot foot collapse on left foot two years foot was reconstructed. The last couple days my right foot has become very swollen. It doesn't necessarily look red and I cannot feel heat I it. I am not diabetic . But last time I had no sign of redness or swelling. I have very large calluses on both feet and see a podiatrist every three weeks for maintenance. Little nervous .. Have an appointment next on day. Do I need to be concerned before then?
