Question:
My 42-month-old daughter is crying at night complaining that her anus is extremely itchy. I applied a soothing ointment and an ophthalmic ointment, but she is still crying from the severe itchiness. Additionally, she cries saying it hurts when she urinates. Could this be because her anus is torn? I searched online and found various causes like parasites, cystitis, or an anal fissure. Will a pediatrician be able to diagnose this if we go to the clinic?
Answer:
It must be very worrying to see your 42-month-old daughter struggling with anal itching at night and pain during urination.
Looking at the symptoms, there are a few possibilities:
[Things to check immediately]
• Check the area around the anus: Is it red and swollen, or are there any visible wounds or cuts?
• Urine color: Is it different from usual, or is there blood mixed in?
• Time of itching: Does it mostly itch only at night?
[Possible causes]
1. Pinworms (parasites): Characterized by severe itching at night.
2. Anal fissure: Tearing caused by constipation.
3. Urinary tract infection: Accompanied by pain during urination.
4. Skin irritation: Due to hygiene products or sweat.
[What you can do right now]
• Sitz bath in lukewarm water (for 5-10 minutes).
• Have her wear pure cotton underwear.
• Trim her fingernails short (to prevent worsening the condition by scratching).
→ Please visit a pediatrician tomorrow morning.
The doctor can examine the area around the anus, perform a urine test, and, if necessary, a pinworm test (clear tape test).
If the symptoms worsen overnight or if she develops a fever, please go to the emergency room.
