Feeling Exhausted and Hot: Could It Be Myocarditis or Endocarditis?

Are you too tired or is it something else?

Hello Doctor: I might not have slept well last night, and today I've felt very tired and a bit feverish all day.
I initially thought about taking a nap this afternoon, but I couldn't fall asleep and felt quite restless.
I can feel my heart beating and sometimes have difficulty breathing, needing to take deep breaths.
I've also noticed a burning sensation in my heart that comes and goes, along with some pain.
I thought riding my bike might help, but after just ten minutes, I realized I was really exhausted, so I stopped.
In the evening, I measured my temperature at home and it was 37 degrees Celsius, which seems like I might have a slight fever.
This makes me think about what I learned in school, and I want to ask the doctor if it could be myocarditis or endocarditis.
I'm really worried!

Hello Mr.
Zhu, based on your description...
you have been feeling very tired and slightly feverish all day.
You initially planned to take a nap this afternoon, but you couldn't fall asleep and felt quite restless.
You can feel your heart beating and sometimes have difficulty breathing, requiring deep breaths.
You also notice occasional sensations of warmth or pain in your heart.
You thought about riding a bicycle to see if it would help, but after just ten minutes, you realized you were too exhausted to continue.
In the evening, you measured your temperature at home and found it to be 37 degrees Celsius, which seems to indicate a slight fever...
Essentially, the diseases you are worried about, such as myocarditis or pericarditis, are premature concerns...
especially the latter, which is a complex issue in cardiology.
Fortunately, the likelihood of these conditions is low; rather, the chances of a common cold or viral infection are much higher...
Try to relax, and if you remain concerned, please consult your trusted family physician nearby.
Take care, Ministry of Health and Welfare Changhua Hospital.

More Info

Feeling exhausted and experiencing a sensation of heat can indeed be concerning, especially when accompanied by symptoms such as palpitations, difficulty breathing, and a feeling of pressure or discomfort in the chest. Your symptoms raise valid questions about potential underlying conditions, including myocarditis or endocarditis, but it’s essential to approach this systematically.

First, let's clarify what myocarditis and endocarditis are. Myocarditis is an inflammation of the heart muscle, often caused by viral infections, autoimmune diseases, or exposure to certain toxins. Symptoms can include chest pain, fatigue, shortness of breath, and palpitations. Endocarditis, on the other hand, is an infection of the inner lining of the heart chambers and valves, typically caused by bacteria entering the bloodstream. Symptoms may include fever, chills, fatigue, and heart murmurs.

Given your symptoms of fatigue, a slight fever (37 degrees Celsius), and the sensation of your heart racing, it’s understandable to be concerned about these conditions. However, it’s important to note that many other factors could contribute to your feelings of exhaustion and heat. Stress, anxiety, lack of sleep, and even dehydration can lead to similar symptoms. Additionally, common viral infections or even a mild flu could cause fatigue and a low-grade fever without necessarily indicating myocarditis or endocarditis.

Your mention of feeling "hot" and having difficulty sleeping could suggest that your body is under some form of stress, whether physical or emotional. Stress can lead to increased heart rate and feelings of anxiety, which might explain the palpitations and the sensation of heat. Furthermore, if you’ve been feeling unwell for a few days, it’s possible that your body is fighting off an infection, which could explain the elevated temperature and fatigue.

In terms of next steps, it’s crucial to monitor your symptoms closely. If you experience any worsening of your symptoms, such as increased chest pain, significant shortness of breath, or persistent high fever, you should seek medical attention immediately. A healthcare professional can perform a thorough evaluation, which may include a physical examination, blood tests, and possibly imaging studies like an echocardiogram to assess heart function and rule out myocarditis or endocarditis.

For now, consider the following recommendations:
1. Rest: Ensure you’re getting adequate sleep and allow your body to recover.

2. Hydration: Drink plenty of fluids to stay hydrated, especially if you have a fever.

3. Stress Management: Engage in relaxation techniques such as deep breathing, meditation, or gentle exercise like walking, which can help alleviate stress and improve your overall well-being.

4. Diet: Maintain a balanced diet rich in fruits, vegetables, and whole grains to support your immune system.

Lastly, if your symptoms persist or you remain concerned about your heart health, it’s advisable to consult with a healthcare provider. They can provide personalized advice and determine if further investigation is warranted based on your medical history and current symptoms. Remember, while it’s good to be aware of potential health issues, many symptoms can have benign explanations, and a healthcare professional can help clarify your situation.
