Oral sores are another hallmark of HFMD. These can appear as small red spots or blisters on the tongue, gums, and insides of the cheeks. These sores can be painful, making it difficult for children to eat or drink.

3. When Refusing To Walk Is A Red Flag — And When It’s Just Painful Blisters

Refusal to walk in toddlers with HFMD is often due to the painful blisters on their feet. These blisters can make standing and walking uncomfortable, leading to a reluctance to move. While this is usually not a cause for alarm, it is important to monitor your child for other symptoms.
If your child shows signs of extreme discomfort, high fever, or if the rash spreads rapidly, it’s crucial to seek medical attention. These can be indicators of more serious complications or a different underlying condition.

4. Other Possible Causes Of Palm-And-Sole Rashes (And How They Differ)

While HFMD is a common cause of rashes on the palms and soles, other conditions can present with similar symptoms. For instance, allergic reactions can cause a widespread rash, though these typically appear on other parts of the body as well.
Kawasaki disease is another, albeit rare, possibility. This condition affects the blood vessels and can cause a persistent high fever, red eyes, and a rash. Immediate medical evaluation is necessary if Kawasaki disease is suspected due to its potential complications.

5. At-Home Checks You Can Safely Do Before You See A Doctor

Before consulting a doctor, there are several at-home checks you can perform. Monitor your child’s temperature regularly to track any fever. Examine the rash closely, noting any changes in appearance or if it spreads.
Ensure your child is staying hydrated, as fever and mouth sores can lead to dehydration. Offer clear fluids and monitor their urine output. If your child is refusing fluids or appears to be in significant pain, seek medical advice.

6. How Contagious Is This Rash — And Who Needs To Stay Home?

HFMD is highly contagious, spreading through contact with respiratory droplets, blister fluid, and feces of an infected person. It’s advisable to keep your child at home and away from daycare or school until all symptoms, especially the fever and open blisters, have resolved.
