Can Intermittent Appearance Of Pus-filled Blisters Be Due To Infection?

My 3-year-old complained once that his ankle was itchy. A day or 2 later, a pus-filled blister appeared. That one broke a couple of days later and I covered it with a bandaid & neosporin, but another one showed up. That one popped, then two more showed up on his other ankle. He has several bumps in both ankles that I assumed were bug bites but he s not bitten anywhere else. Could it be an infection?

Pediatrician,  's  Response
Hi, I had gone through your question and understand your concerns.

From description it appears to be pyoderma/ impetigo which is spreading from one site to another due to getting infected by pus from one lesion to another site like scratching by fingers.
It is more common in humid and hot environment like rainy season . It needs to be treated with oral and topical antibiotics after confirming the diagnosis by your doctor or paediatrician. Mild lesions may respond to topical antibiotics alone.

To prevent its spread make habit of hand washing and keep good hygiene . If it is recurring over a long period it may require long topical application of antibiotics at reservoir of infection.

Hope this answers your question. If you have additional questions then please do not hesitate in writing to us.

Wishing your child good health.
