Hi. Greetings, Don't use a a corn cap, the skin will become very soggy and heal slowly. Better you use a salicylic acid paste 12 % daily night and Vaseline jelly daily morning. This would help in keeping skin soft. Wear soft padded foot wear . this is most important to prevent recurrence. Hope this helps. For further queries, send message on private follow up chat or see a dermatologist near you. Dr Govind Suresh Mittal, Excel care hospital, Bangalore.
