Hello, Thanks for the query, You might have developed fungal infection. Your description matches with that. Usually fungal infections are itchy and recurrent. Please get a KOH mount done, This can confirm the fungal etiology. Treatment can be with oral antifungals as well as with topical antifungals. Treatment must be continued for at least a month to prevent recurrence. Please meet a dermatologist for exact diagnosis. Let me know if you have any other doubt. You can ask a direct question to me on this forum, following the below link.https
