Detailed Answer:
Hello,
Welcome to healthcare magic.

I understand from your query that your 2 year old daughter had a lesion on her foot of 1 day duration.

Based on your history and description, I would consider the possibility of Angioedema and Impetigo.

Brief Answer:
? Frictional Blisters

Detailed Answer:
Hello,

Greetings.

I noted your additional history.

I have seen the clinical pictures attached in your other query ( Answered by Dr. XXXXXXX Hiremath) as the images are not seen on my page.

I do not see much redness on her foot. There are 2-3 small blisters with clear fluid and no pus.

From your additional history, I would consider the possibility of Friction induced blisters possibly from the sandals.

You could apply an antibiotic cream containing 2 % Mupirocin twice a day for about 5 days so as to prevent infection.

Please make sure she wears soft footwear which do not cause friction especially in the affected area.

If she develops a fever or if the foot appears swollen/ red, it would suggest an infection. She would need an oral antibiotic like Amoxycillin or Cephalexin for 3-5 days.

Insect bites could also present with blisters. However, they have redness around the blisters and respond to topical hydrocortisone. Since it has not responded, I would possibly rule it out.

Hope this helps you.

If you have any more queries, I will be glad to answer.

Take care.

Regards,
Dr. Johny Chacko
