My daughter started to develop a rash on her feet and ankles on 6/24/15. She had worn new espadrille shoes for the first time with a raffia type sole on them on 6/22. The rash didn t start to appear until 6/24. The rash did not have the shape of the shoe on her foot when it started and it was 2 days after the new shoes. I am not thinking it is really from the shoes. She went to a Minute Clinic in CVS who gave her a prednisone pack on 6/25, but she was going out with friends and having a drink, so she did not start the pack. Now the rash is spreading up her legs and feet are swelling. We are going to the ER now. Do you have an idea of what this might be?
