Thanks for the query,
You might have developed fungal infection
Probably a candida infection.
Your description matches with this.
Please get a KOH mount done from material obtained from the lesions.
This can confirm the fungal etiology.
Treatment can be with oral antifungals as well as with topical antifungals.
Please meet a dermatologist
for exact diagnosis.
