Unexplained Fever: When to Seek Medical Attention for Your Symptoms

Fever of unknown origin (FUO)

Hello, I would like to ask a question.
Recently, I have been experiencing unexplained heat in my head and a feeling of internal heat in my body.
I have researched various related materials, but some indicate that it is not serious, while others suggest immediate medical attention.
This issue has been troubling me for a long time, so I would appreciate your help in answering my concerns.
Over the past three weeks, I have experienced the following symptoms: three weeks ago, I had unexplained diarrhea for nearly a week, during which I needed to use the restroom every two to three hours.
In the past two weeks, I have had unexplained fevers, with no specific timing for when they occur.
When I have a fever, I also experience headaches and soreness in my neck and shoulders.
During this time, I visited an ophthalmologist due to eye pain, and the examination revealed conjunctivitis.
Additionally, I sometimes notice small red spots that are neither painful nor itchy, which appear to be allergic reactions.
In the last two days, I have frequently felt dryness in my throat, and sometimes I have phlegm, which occasionally has a bit of blood when I cough it up.
However, I do not have a persistent cough; sometimes, I only have a dry cough briefly.
Based on these symptoms, I am unsure if this is serious.
If medical attention is necessary, which specialty should I consult? Thank you for your assistance.
^^

The symptoms you described involve several organ systems, including the gastrointestinal tract, respiratory system, skin, and eyes.
Therefore, it is more likely to be caused by a systemic disease, such as an autoimmune disorder or infection.
You should first determine if you have a fever, so please record your temperature multiple times throughout the day.
If you do have a fever, please consult an infectious disease specialist.
If not, you may start by seeing a primary care physician.

More Info

When experiencing unexplained fever and associated symptoms, it is crucial to understand the potential underlying causes and when to seek medical attention. Based on your description, you have been experiencing a range of symptoms over the past few weeks, including unexplained fever, abdominal issues, headaches, neck and shoulder pain, and respiratory symptoms such as dry throat and occasional blood-tinged phlegm. These symptoms can be indicative of various medical conditions, some of which may require prompt evaluation and treatment.

Firstly, the presence of fever, especially when it is recurrent or persistent, is often a sign that your body is fighting an infection or dealing with inflammation. Infections can be viral, bacterial, or even fungal, and they can affect various systems in the body. Given your history of diarrhea, which lasted for about a week, it is possible that you may have had a gastrointestinal infection that could have contributed to your current symptoms. Gastrointestinal infections can sometimes lead to systemic symptoms, including fever and malaise.

The headaches, neck and shoulder pain you are experiencing could be related to tension or could indicate a more systemic issue, such as meningitis or another type of infection that affects the central nervous system. While these conditions are less common, they are serious and warrant immediate medical attention.

The symptoms of dry throat and blood-tinged phlegm raise additional concerns. Blood in phlegm can be a sign of several conditions, ranging from minor issues like irritation or infection in the throat to more serious conditions such as pneumonia or even pulmonary embolism. Given that you have also experienced conjunctivitis (inflammation of the eye), it is important to consider whether there is a systemic infection that could be affecting multiple systems in your body.

In your case, it is advisable to seek medical attention, especially since your symptoms have persisted for several weeks and are accompanied by fever. You should consider visiting a healthcare provider who specializes in infectious diseases or a general practitioner who can perform a thorough evaluation. They may recommend laboratory tests, such as blood tests, sputum cultures, or imaging studies like a chest X-ray, to determine the underlying cause of your symptoms.

In summary, while some mild fevers and associated symptoms can resolve on their own, your persistent symptoms, especially the combination of fever, gastrointestinal issues, respiratory symptoms, and conjunctivitis, suggest that a more serious underlying condition may be present. It is better to err on the side of caution and seek medical evaluation to rule out any serious infections or other health issues. Early diagnosis and treatment can significantly improve outcomes and help alleviate your symptoms more effectively.
