Persistent High Fever in My 4-Year-Old: What Should I Do?

If your daughter's body temperature is consistently elevated, what should you do?

My daughter is 4 years old.
In mid-March, she was hospitalized for 6 days due to bronchitis and otitis media with a high fever, and she was on antibiotics for over two weeks.
After being discharged, she experienced recurrent fevers 3 to 4 times until late April, with the highest temperature reaching 38.6°C (ear temperature) accompanied by a cough.
When she is not feverish, her daytime temperature consistently stays around 37.2 to 37.5°C.
If she sweats from activity, her temperature may drop back to around 36.7°C, but it quickly rises again to about 37.2 to 37.5°C (she has a history of allergies).
At night, her temperature is around 36.7°C, but she has trouble sleeping, often tossing and turning.
After waking up, her temperature tends to spike.
When she has a fever, we consulted a doctor who only diagnosed her with a common cold.
However, her temperature continued to fluctuate, so we sought traditional Chinese medicine (concerned about the excessive use of Western medications) to also address her allergic constitution.
The Chinese medicine practitioner mentioned that her immune system is quite low and attributed her elevated temperature to her constitution (without conducting any specific tests).
Is this really the case? I noticed this pattern started after her hospitalization, and it hasn't been like this before.
Occasionally, she complains of stomach discomfort, but when I ask if her stomach hurts, she says no, just that it feels uncomfortable, and she has no diarrhea; her bowel movements are normal.
Her energy levels and appetite are okay, but I feel her complexion isn't great, especially under her eyes (the bags are often red and feel a bit warm).
I'm worried that there might be some underlying issue that we are unaware of, which could delay necessary medical attention.
Therefore, I would like to ask the doctor if it is normal for a child to have consistently elevated temperatures like this.
Should we go to the hospital for an examination? Which department should we consult? What specific tests should we ask the doctor to perform? Could her symptoms be indicative of a urinary tract infection or vesicoureteral reflux? I am a very anxious mother, so seeing my daughter like this makes me very worried, and I don't know what to do.

There are many causes of fever in children, such as infections (the most common), autoimmune diseases, tumors, drug fever, and summer heat, among others.
Depending on the situation, it is advisable for your child to go to the hospital for examination (as there are diagnostic facilities available).
Since infections are the most prevalent cause in children, it is recommended to consult a pediatric infectious disease specialist.
Typically, basic blood tests, inflammatory markers, and urine tests will be performed.
If more specialized tests are needed, the physician will arrange them accordingly.

More Info

Persistent high fever in children can be a source of significant concern for parents, especially when it follows a recent illness like bronchitis or otitis media, as in your daughter's case. Given her history of hospitalization and antibiotic treatment, it is understandable that you are worried about her ongoing symptoms.

First, it's important to recognize that fever is a natural response of the body to infection. In children, it is common for fevers to fluctuate, especially after a recent illness. The fact that your daughter’s fever reaches up to 38.6°C (101.5°F) and is accompanied by a cough suggests that her body is still fighting off an infection. However, persistent fever, especially if it recurs multiple times, warrants further investigation.

In your daughter's situation, there are several potential causes for her recurrent fevers and elevated baseline temperature. These could include:
1. Post-Infectious Inflammation: After a significant infection, the body can remain in a heightened state of inflammation, which may cause intermittent fevers.

2. Viral Infections: Some viral infections can cause prolonged fevers even after the acute phase has resolved. These can include common viruses that affect the respiratory tract.

3. Allergic Reactions: Given that your daughter has a history of allergies, it is possible that her symptoms could be exacerbated by environmental allergens, leading to inflammation and fever.

4. Underlying Conditions: While less common, persistent fevers can sometimes indicate underlying conditions such as autoimmune diseases or chronic infections.
5. Urinary Tract Infections (UTIs): UTIs can also present with fever and may not always show typical symptoms in young children. The fact that you mentioned her occasionally feeling discomfort in her abdomen could be a sign worth investigating.

Given these possibilities, it is advisable to consult a pediatrician for a thorough evaluation. Here are some steps you can take:
- Visit a Pediatrician: Schedule an appointment with your child's pediatrician. They can perform a comprehensive physical examination and assess her overall health.

- Diagnostic Tests: The doctor may recommend blood tests to check for signs of infection or inflammation, a urinalysis to rule out a UTI, and possibly imaging studies if they suspect any underlying issues.

- Monitor Symptoms: Keep a detailed record of her symptoms, including the frequency and duration of fevers, any associated symptoms (like cough, abdominal discomfort, or changes in appetite), and any environmental factors that may trigger her allergies.

- Consider Allergy Management: If allergies are suspected to be contributing to her symptoms, discussing management strategies with an allergist may be beneficial.

- Follow-Up: If her symptoms persist or worsen, ensure that you follow up with her healthcare provider. Persistent symptoms warrant ongoing evaluation to rule out any serious conditions.

In conclusion, while it is common for children to experience fluctuations in temperature following an illness, persistent high fever and other symptoms should not be ignored. Consulting with a healthcare professional will provide clarity and help ensure that your daughter receives the appropriate care. Your vigilance as a parent is crucial in navigating her health concerns, and seeking medical advice is the best course of action.
