Unlikely: Athlete's foot does not usually get swollen although you may have scaly and itchy skin from it. It is hard to tell what the exact problem is but if the antibiotic eliminates the swelling within a few days, then the swollen feet is likely from an infection. if not, you will need to keep on looking for the answer. See derm if necessary.
