Persistent fever

Fever that comes and goes for 12 days, with the doctor prescribing antibiotics and drawing blood? There are signs of inflammation, but otherwise, everything is fine (not sure about the purpose of the blood test).
I haven't taken any medication, but I experience a spike in fever every day, reaching over 38 degrees Celsius, along with a cough and phlegm.
I've been drinking plenty of fluids, and there are no other unusual symptoms.
What could be causing this? Should I go get medication or continue to observe for a while? Is this contagious?

More Info

Persistent fever lasting for 12 days can be a concerning symptom that warrants careful evaluation and management. The fact that you have experienced intermittent fevers reaching over 38 degrees Celsius, along with coughing and sputum production, suggests that there may be an underlying infectious process or another medical condition that needs to be addressed.

Causes of Persistent Fever
Fever is a common response of the body to infection, inflammation, or other medical conditions. The causes of persistent fever can be broadly categorized into infectious and non-infectious causes:
1. Infectious Causes:
- Bacterial Infections: Conditions such as pneumonia, urinary tract infections, or sepsis can lead to prolonged fever. Given your symptoms of cough and sputum, a respiratory infection like pneumonia should be considered.

- Viral Infections: Certain viral infections can cause prolonged fever, although they often resolve on their own.

- Parasitic Infections: In some regions, infections like malaria can cause persistent fever.

2. Non-Infectious Causes:
- Autoimmune Diseases: Conditions like lupus or rheumatoid arthritis can lead to fever due to inflammation.

- Malignancies: Certain cancers can present with fever as a symptom.

- Drug Reactions: Some medications can cause fever as a side effect.

Diagnostic Approach
The fact that your doctor has ordered blood tests is a positive step towards identifying the cause of your fever. Blood tests can help assess for signs of infection (such as elevated white blood cell counts), inflammation (such as elevated C-reactive protein), or other abnormalities. The purpose of these tests is to rule out serious conditions and guide treatment.

Treatment Options
1. Antibiotics: If a bacterial infection is suspected, antibiotics may be necessary. It is crucial to take the full course of antibiotics as prescribed, even if you start feeling better before finishing the medication.

2. Symptomatic Treatment: Over-the-counter medications like acetaminophen or ibuprofen can help reduce fever and alleviate discomfort. However, it is important to follow the dosing instructions and consult your doctor if you have any concerns.

3. Hydration: Staying well-hydrated is essential, especially if you are experiencing fever and sweating. Drinking plenty of fluids can help maintain hydration and support your immune system.

When to Seek Further Help
If your fever persists despite treatment, or if you develop new symptoms such as difficulty breathing, chest pain, or severe fatigue, it is important to seek medical attention promptly. Additionally, if you notice any signs of dehydration (such as dark urine, dizziness, or confusion), you should seek help immediately.

Contagiousness
Regarding the question of whether your condition is contagious, it depends on the underlying cause of your fever. If your fever is due to a viral or bacterial infection, there may be a risk of transmission to others. It is advisable to practice good hygiene, such as frequent handwashing and avoiding close contact with others, until you have a clearer understanding of your diagnosis.

Conclusion
In summary, a persistent fever lasting 12 days is a significant symptom that requires thorough evaluation. It is essential to follow up with your healthcare provider, adhere to prescribed treatments, and monitor your symptoms closely. If you have any concerns or if your condition worsens, do not hesitate to seek further medical attention. Your health and well-being are paramount, and timely intervention can lead to better outcomes.
