Persistent fever?


I would like to ask about my condition.
Four days ago, I had a fever and went to the clinic that night for a rapid test, which showed negative results for both influenza A and B.
However, after taking the medication, I continued to have a fever that fluctuates daily, consistently experiencing fever in the morning and evening.
After four days, I visited my family doctor, who conducted blood tests, a urine test, and a chest X-ray, all of which came back normal.
I was prescribed three courses of antibiotics, but I still feel unwell.
There are people around me with influenza B.
My fever has reached 40 degrees Celsius, and I feel dizzy, especially on the third and fourth days.
My stomach has been uncomfortable, and I have had no appetite all day, along with nausea.
I also experience chest pain when I cough, and I have to hold my chest each time I cough.
Additionally, I have been sweating profusely on my forehead for no apparent reason.
The main issue is my stomach discomfort persists despite taking antacids.
What should I do about this?

A negative rapid influenza test does not rule out influenza (as the accuracy of the rapid test is about 60%).
Your symptoms still resemble those of influenza, so it may be worth considering a repeat rapid test or directly administering antiviral medications.
If the fever persists, further blood tests and a chest X-ray may be warranted, as being normal at one point does not guarantee that it will remain normal in two to three days; the condition can change rapidly.
Additionally, there are many potential causes for fever, so consulting a pediatric infectious disease specialist may be advisable.

More Info


Persistent fever in children can be a challenging issue for parents, especially when the cause is not immediately clear. In your case, it seems that your child has been experiencing a fever for several days, along with other symptoms such as gastrointestinal discomfort, nausea, and chest pain upon coughing. Given the complexity of your child's symptoms and the duration of the fever, it is essential to approach this situation with caution and seek appropriate medical guidance.


Understanding Persistent Fever
Fever is a common response to infection, inflammation, or other medical conditions. In children, it can be caused by a variety of factors, including viral infections (like influenza), bacterial infections, or even non-infectious causes such as autoimmune diseases or inflammatory conditions. The fact that your child tested negative for influenza A and B is a good start, but it does not rule out other viral infections or bacterial infections.


When to Seek Medical Help
1. Duration of Fever: If a fever persists for more than three days, it is advisable to seek medical attention. In your case, since the fever has lasted for four days, it is appropriate to consult a healthcare provider.

2. Severity of Symptoms: High fevers (above 39°C or 102°F) that are accompanied by severe symptoms such as persistent vomiting, dehydration, difficulty breathing, or severe abdominal pain warrant immediate medical evaluation.

3. Response to Medication: If your child is not responding to over-the-counter medications (like acetaminophen or ibuprofen) and continues to have high fevers, this is another indicator that further medical evaluation is necessary.

4. Associated Symptoms: Symptoms such as chest pain, significant gastrointestinal discomfort, or neurological signs (like confusion or lethargy) should be taken seriously and evaluated promptly.


Recommended Actions
1. Follow-Up with Healthcare Provider: Since your child has already seen a doctor and had tests done, it may be beneficial to follow up with the same provider or seek a second opinion if symptoms persist. Ensure that you communicate all symptoms clearly, including the fever pattern, gastrointestinal issues, and any other concerns.

2. Consider Further Testing: If the fever continues without a clear diagnosis, your healthcare provider may recommend additional tests, such as blood cultures, imaging studies, or even a referral to a pediatric specialist.

3. Monitor Symptoms: Keep a detailed log of your child's symptoms, including fever patterns, any new symptoms, and how they respond to medications. This information can be invaluable for healthcare providers in determining the next steps.

4. Hydration and Nutrition: Ensure your child stays hydrated, especially if they are experiencing gastrointestinal symptoms. Offer clear fluids and, if tolerated, bland foods. Avoid forcing food if they have no appetite, as this can lead to further discomfort.

5. Rest and Comfort: Encourage your child to rest as much as possible. Use cool compresses or a lukewarm bath to help manage fever and provide comfort.


Conclusion
In summary, persistent fever in children can be concerning, and it is essential to monitor the situation closely. Given your child's symptoms and the duration of the fever, it is advisable to maintain communication with healthcare providers and consider further evaluation if symptoms do not improve. Remember, while fever is often a sign of the body fighting an infection, persistent or high fevers, especially when accompanied by other concerning symptoms, should not be ignored. Your child's health and comfort are paramount, and seeking timely medical advice is the best course of action.
