Hello there I have read through your question and would like to tell you that there are many conditions which can lead to ankle swelling, but since you have mentioned that you suspect it may be due to the shoes therefore according to me it was caused due to prolonged pressure. I would advise you to keep your feet raised on an elevated surface. Take an antiinflammatory like aceclofenac to reduce the inflammation. Get the following investigations done, ESR and CRP. If your swelling doesn't subside in one week you should consult your physician . I hope that answers your question. If you have any further questions please feel free to write. Thank you for choosing healthcare magic.
