Waking up to see a red, spreading circle on your child’s arm—especially when it’s causing intense itching and tears—can be alarming. While it’s important to stay calm, taking prompt action is essential for relief and to prevent the rash from worsening.
Here’s a step-by-step guide on what could be happening, what to do immediately, and when to seek medical care.
1. Could It Be Ringworm?
Despite the name, ringworm isn’t caused by a worm—it’s a fungal infection called tinea. Signs include:
-
A circular red rash with a clear or scaly center
-
Raised, distinct edges giving a ring-like appearance
-
It may start small and grow rapidly
Children are more susceptible because of close contact with other kids, pets, or contaminated surfaces. Warm, moist environments also encourage fungal growth.
2. Immediate Steps to Take
-
Wash the area gently with mild soap and lukewarm water
-
Pat dry; avoid rubbing
-
Keep nails trimmed to prevent scratching and potential infection
-
Apply a cool compress for relief
-
Leave the rash uncovered if possible to let the skin breathe
3. How to Tell Ringworm from Other Rashes
-
Lyme Disease: Usually a bullseye rash with flu-like symptoms
-
Hives: Raised, itchy welts appearing anywhere on the body, often due to allergies
-
Eczema: Red, inflamed patches that are dry and flaky, not circular
Ringworm is usually a single or multiple circular lesion with well-defined edges.
4. When to Call a Doctor Immediately
Seek medical attention if:
-
The rash spreads rapidly
-
It causes severe itching
-
Your child has a fever
-
Over-the-counter treatments aren’t working
-
Your child has a weakened immune system
