Persistent Heat Sensation: A Neurological Perspective - Neurology

More Info

---

The sensation of persistent heat in the body, especially when accompanied by fatigue, dry mouth, and other symptoms, can be quite concerning. From a neurological perspective, it is essential to consider various factors that could contribute to this sensation, particularly in the context of your recent health history.

Firstly, it is important to differentiate between actual fever and the subjective feeling of heat. As you mentioned, your body temperature has remained around 36.8°C, which is within the normal range. This discrepancy between your perceived heat and the actual temperature can be attributed to several factors, including anxiety, hormonal fluctuations, or even environmental conditions such as weather changes. Anxiety, in particular, can heighten your sensitivity to bodily sensations, making you feel warmer than you actually are.

Given your recent history of viral infection, it is also crucial to consider the aftereffects of such illnesses. Viral infections can lead to post-viral fatigue syndrome, where individuals experience prolonged fatigue and other symptoms even after the acute phase of the illness has resolved. This condition can sometimes manifest as a persistent feeling of warmth or heat in the body, despite normal temperature readings.
Moreover, the body's thermoregulation can be influenced by various factors, including hydration levels, metabolic rate, and even stress. Dehydration can lead to a sensation of heat, as can increased metabolic activity due to stress or anxiety. It is also worth noting that certain medications or supplements can affect body temperature regulation, so reviewing any recent changes in your medication or supplement intake with your healthcare provider may be beneficial.

In your case, since you have already consulted with a hematologist regarding your previous blood test results, it would be prudent to follow up with a primary care physician or a neurologist to further explore the neurological aspects of your symptoms. They may recommend additional tests to rule out any underlying conditions that could be contributing to your persistent heat sensation.
Additionally, if you are experiencing significant anxiety regarding your health, it may be helpful to speak with a mental health professional. Anxiety can exacerbate physical symptoms, and addressing the psychological component may alleviate some of the physical sensations you are experiencing.

In summary, while your persistent sensation of heat may be influenced by various factors, including recent viral infections, anxiety, and environmental conditions, it is essential to consult with a healthcare professional to rule out any underlying medical issues. Keeping a symptom diary, noting when the sensation occurs and any accompanying symptoms, can also provide valuable information for your healthcare provider in determining the cause and appropriate management of your condition.
