This is probably a good case for daily warm soaks to the feet for a few days. Betadine can be added to the water or you can use Epsom salts or table salt. Don’t massage the feet or legs though.
She might lose the toe tips on the right foot. The left foot from the first pics of the bottom, and the swelling today could mean that she loses much of the left foot. I hope not, but taking pictures every day or two will document this. She could still get around with one mostly normal foot.
