Physical discomfort?


Hello, doctor.
Two months ago, I had a fever of unknown origin that lasted for a day and a half.
I visited a clinic, and the doctor said it was a cold, but I did not have any cold symptoms.
Recently, I occasionally feel heat in my head, but I do not have a fever.
When I exhale, I can feel warm air in my nasal passages and throat.
I also occasionally experience dizziness, tinnitus, and headaches, which do not have a specific location.
What could be the cause of this?

Hello, if you have a fever, it is important to primarily monitor your body temperature.
If the aforementioned symptoms do not improve, it is recommended to consult an otolaryngologist at Changhua Hospital for further evaluation.

Understanding unexplained symptoms such as fever, headaches, and other discomforts can be quite challenging, especially when the symptoms do not align with typical diagnoses like the common cold or flu. Based on your description, it seems that you have been experiencing a range of symptoms, including intermittent fever, headaches, dizziness, and sensations of heat in your head and throat.
Firstly, it’s important to understand that headaches can arise from various causes, and they can be classified into primary and secondary headaches. Primary headaches, such as tension-type headaches and migraines, are not caused by underlying medical conditions. Secondary headaches, on the other hand, are symptoms of another health issue, which could range from infections to more serious conditions like neurological disorders.

Given your history of fever without typical cold symptoms, it’s possible that you may have experienced a viral infection that did not manifest in the usual ways. Viral infections can sometimes cause fever and malaise without the classic symptoms of a cold, such as a runny nose or cough. The fact that you felt better after a day suggests that your body was able to fight off the infection, but lingering symptoms like headaches and dizziness can occur as your body recovers.

The sensation of heat in your head and throat, along with headaches and dizziness, could indicate several possibilities. One common cause could be tension headaches, which can be exacerbated by stress, anxiety, or prolonged periods of screen time, especially if you spend long hours in front of a computer. This type of headache often presents with a feeling of tightness or pressure around the forehead or back of the head and neck.

Another possibility is that you may be experiencing symptoms related to sinus issues. Sinusitis, or inflammation of the sinuses, can cause headaches, facial pain, and a feeling of pressure in the head, along with a sensation of heat. If you have had any recent upper respiratory infections, this could be a contributing factor.

Dizziness and tinnitus (ear ringing) can also be associated with several conditions, including inner ear issues, which can affect balance and hearing. Conditions like vestibular neuritis or Meniere's disease could lead to these symptoms, particularly if they are accompanied by headaches.

Given the complexity of your symptoms, it is advisable to consult a healthcare professional for a thorough evaluation. A neurologist or an ear, nose, and throat (ENT) specialist may be particularly helpful in diagnosing the underlying cause of your headaches and other symptoms. They may recommend imaging studies, such as an MRI or CT scan, to rule out any serious conditions, especially if your symptoms persist or worsen.

In the meantime, it may be beneficial to keep a symptom diary, noting when your symptoms occur, their intensity, and any potential triggers. This information can be invaluable for your healthcare provider in determining the best course of action.

Lastly, managing stress, ensuring adequate hydration, maintaining a balanced diet, and getting regular sleep can help alleviate some of your symptoms. If you find that your symptoms are significantly impacting your daily life, do not hesitate to seek medical attention sooner rather than later. Your health is paramount, and understanding the root cause of your symptoms is essential for effective treatment.
