Chest Pain, Breathing Issues, and Rapid Heartbeat: Flu or Side Effects? - Cardiology

Chest tightness, difficulty breathing, and rapid heartbeat?


Yesterday, I went to an ENT specialist due to a fever of 39 degrees Celsius, sore throat, body aches, a little runny nose, and nasal congestion.
The doctor said I have a flu-like illness, so I took medication for a day.
However, when I woke up the next day, I felt chest tightness, difficulty breathing, and a rapid heartbeat, with the chest tightness lasting over half an hour.
Is this a side effect of the medication, or could it be a complication of the flu? The medications prescribed include Strocain, Voren, Pseudoephedrine, Allegra, Panadol (which I haven't taken yet), and Eraflu.
I also have mitral valve prolapse.
Could the chest tightness and pain be simply due to that? I'm really scared it might be a complication from the flu; I read online about myocarditis, pneumonia, and so on...

More Info


The symptoms you are experiencing—chest pain, difficulty breathing, and rapid heartbeat—can be concerning, especially following a recent illness like flu or flu-like symptoms. Given your medical history of mitral valve prolapse, it is essential to approach this situation with caution.

Firstly, let's address the potential causes of your symptoms. The medications you mentioned—Strocain, Voren, Pseudoephedrine, Allegra, Panadol, and Eraflu—are commonly used to treat flu-like symptoms, such as fever, sore throat, and nasal congestion. While these medications can be effective, they may also have side effects. For instance, Pseudoephedrine, a decongestant, can lead to increased heart rate and feelings of anxiety or restlessness, which might explain your rapid heartbeat and discomfort.
Moreover, the combination of medications can sometimes lead to unexpected interactions, especially if you have underlying health conditions like mitral valve prolapse. Mitral valve prolapse can cause symptoms such as palpitations, chest pain, and anxiety, which may be exacerbated by medications or stress.
On the other hand, your symptoms could also be related to complications from the flu. While serious complications like myocarditis (inflammation of the heart muscle) or pneumonia are possible, they are relatively rare in otherwise healthy individuals. However, if you have a pre-existing heart condition, you may be at a slightly higher risk for such complications.
It's important to note that anxiety and stress can also manifest as physical symptoms, including chest pain and difficulty breathing. Given that you are feeling anxious about your symptoms, this could be contributing to your discomfort. Anxiety can lead to hyperventilation, which can cause chest tightness and a rapid heartbeat, further complicating your situation.

Given the complexity of your symptoms and your medical history, it is advisable to seek immediate medical attention. A healthcare professional can perform a thorough evaluation, including a physical examination, an electrocardiogram (ECG), and possibly an echocardiogram to assess your heart function and rule out any serious complications.
In the meantime, try to remain calm and avoid any activities that may exacerbate your symptoms. If you experience severe chest pain, shortness of breath, or any other alarming symptoms, do not hesitate to seek emergency care.
In summary, while your symptoms could be related to medication side effects, anxiety, or complications from your recent illness, it is crucial to consult with a healthcare provider for an accurate diagnosis and appropriate management. Your health and peace of mind are paramount, and addressing these symptoms promptly will help ensure your well-being.
