Can the mechanism of fever be disrupted?

A year ago, I was infected with extrapulmonary tuberculosis and have been on medication for 270 days.
However, when I first became ill, I experienced significant fluctuations in body temperature, alternating between chills and fever, but I did not see a doctor at that time.
After my diagnosis, I stopped having fevers.
Although I still occasionally feel fluctuations in temperature, they are not as extreme as before.
Perhaps it’s just my nerves, or maybe my fever response mechanism is impaired.
Thank you for your help, doctor!

More Info

The experience of fluctuating body temperatures, often described as "fever" or "chills," can be concerning, especially following a significant health issue like tuberculosis (TB). In your case, having undergone treatment for extrapulmonary tuberculosis for 270 days, it is understandable to question whether your fever response mechanism has been compromised.

Firstly, it is essential to recognize that the body's thermoregulatory system, which controls body temperature, can be influenced by various factors, including infections, medications, and individual physiological responses. Tuberculosis, particularly when it affects the lungs or other parts of the body, can indeed lead to fever as part of the immune response. However, once the infection is treated effectively, the fever typically resolves.

In your situation, the initial experience of significant temperature fluctuations could have been a direct result of the TB infection and the body's immune response to it. After treatment, the absence of fever is a positive sign, indicating that the infection may have been successfully managed. However, the occasional sensation of feeling hot or cold without a significant change in actual body temperature could be attributed to several factors:
1. Post-Infectious Symptoms: After a prolonged illness, some individuals may experience lingering symptoms, including temperature dysregulation. This phenomenon can occur as the body readjusts after fighting off an infection.

2. Psychological Factors: Anxiety and stress can also manifest physically, leading to sensations of chills or warmth. If you are feeling anxious about your health following your TB treatment, this could contribute to your perception of fluctuating temperatures.

3. Hormonal Changes: Hormonal fluctuations, particularly in women, can lead to sensations of heat or cold. This is often cyclical and may not be related to any underlying illness.

4. Other Medical Conditions: Conditions such as hyperthyroidism, infections, or autoimmune disorders can also lead to abnormal temperature regulation. If these symptoms persist or worsen, it would be prudent to consult a healthcare professional for further evaluation.

Regarding your concern about whether your fever response mechanism is "broken," it is important to note that the body’s ability to mount a fever response can vary among individuals, especially after significant illnesses. While some people may experience a diminished fever response after a severe infection, others may not notice any changes.
If you are experiencing persistent symptoms or if your sensations of temperature fluctuations are accompanied by other concerning symptoms (such as weight loss, persistent cough, or fatigue), it would be advisable to seek medical attention. A healthcare provider can perform a thorough evaluation, which may include blood tests, imaging studies, or referrals to specialists, to rule out any underlying issues.

In conclusion, while it is possible for the fever response to be altered following a significant illness like tuberculosis, many factors can contribute to sensations of temperature fluctuations. Monitoring your symptoms and consulting with a healthcare professional if they persist is the best course of action. Your health and well-being are paramount, and addressing any concerns with a qualified provider will help ensure you receive the appropriate care and guidance.
