Question:
My 4-year-old child (weighing 18.5kg) woke up complaining of intermittent pain in the left ear. We visited the pediatrician in the morning, and the doctor said there was earwax close to the eardrum, which might be causing the discomfort. We were sent home without a prescription.
However, the ear pain continued, and by the afternoon, my child developed a fever of 38.6°C. They are in so much pain that they can't even blow their nose, and the fever is still ongoing.
Can earwax alone cause a fever? Is it possible that the earwax kept irritating the ear, or could an ear infection (otitis media) have developed rapidly since the morning visit? My child is crying constantly and cannot even lie down because of the pain. We plan to see the doctor again tomorrow morning, but my child can't sleep at all right now. What can I do to help?
Answer:
It is heartbreaking to watch your child suffer from ear pain and a fever, especially when they cannot sleep at night.
Based on the symptoms you described, there is a high probability that your child has developed an ear infection (otitis media). The combination of ear pain, a 38.6°C fever, inability to blow the nose, and the inability to lie down (which is a classic symptom of an ear infection as lying flat increases ear pressure) suggests that the condition has worsened since your morning visit.
To answer your question directly: earwax does not directly cause a fever. It is highly likely that an ear infection was in its very early stages and progressed rapidly after your morning evaluation.
Immediate steps you can take at home to ease the pain:
Give pain relievers/fever reducers: Based on your child's weight (18.5kg), you can safely administer:
Acetaminophen: About 5.8 ml (185 mg) every 4-6 hours.
Ibuprofen: About 4.6 ml (185 mg) every 6-8 hours.
If the fever or pain remains severe, you can alternate between these two medications every 2-3 hours.
Adjust sleeping posture: Elevate your child's upper body using 2-3 pillows so they are in a semi-sitting position. This helps reduce the pressure build-up inside the ear.
Apply a warm compress: Place a warm towel around the outside of the ear to soothe the pain (do not put anything inside the ear).
Encourage hydration: Ensure your child drinks plenty of fluids.
When to visit the Emergency Room:
Please go to the ER immediately if you notice any of the following warning signs:
Fluid, pus, or blood draining from the ear.
Pain that is completely unmanageable even after giving pain relievers.
A persistent high fever of 39.5°C or higher.
A stiff neck, severe lethargy, or decreased consciousness.
Right now, managing your child's pain and fever with medication is your most important priority to help them rest. Please follow up with your pediatrician tomorrow morning for a re-evaluation, as an antibiotic prescription will likely be needed to properly treat the infection.
