Hello, The blisters on the feet seem to be related to athletes foot which is a fungal infection. I suggest using anti fungal cream for local application such as Miconazole cream. I also recommend using Diflucan. In case of itching, you can use Cetirizine. Hope I have answered your query. Let me know if I can assist you further.
