Sudden Left Chest Pain: Is It Anxiety or a Heart Issue? - Cardiology

Sudden pain in the left chest?


Hello, doctor.
Recently, I have been experiencing shortness of breath and palpitations, so I visited the hospital and consulted with a pulmonologist.
I had a chest X-ray and an electrocardiogram, both of which showed no issues.
I also had my thyroid checked, and all the values were normal.
Therefore, the doctor diagnosed me with autonomic nervous system dysregulation.
However, in the past couple of days, I still experience sudden shortness of breath, and after these episodes, I suddenly feel a sharp pain in a specific spot on my left chest.
Could this be caused by hyperventilation and anxiety? Should I see a cardiologist for further evaluation? Thank you.

Hello: There are many causes of chest pain, including musculoskeletal pain from the chest wall, inflammation of the lungs or airways, heart problems, gastroesophageal reflux, endocrine disorders, or psychological stress, among others.
Given your age, it is less likely to have significant heart or lung issues.
If the basic chest X-ray and electrocardiogram are normal, you can feel more at ease.
If the symptoms persist, consider consulting a cardiologist.

More Info


Sudden left chest pain can be a concerning symptom, especially when accompanied by difficulty breathing and palpitations. Given your recent medical evaluations, including chest X-rays and an electrocardiogram (ECG), which returned normal results, it is understandable to feel anxious about the possibility of a heart issue. However, based on the information provided, it seems more likely that your symptoms may be related to anxiety or a condition known as dysautonomia, which involves the autonomic nervous system.

Anxiety can manifest in various physical symptoms, including chest pain, shortness of breath, and palpitations. This is often due to hyperventilation, where rapid or deep breathing can lead to a decrease in carbon dioxide levels in the blood, causing sensations of lightheadedness, chest tightness, and even pain. The pain you describe as a "point" in your left chest could be a result of muscle tension or irritation of the nerves in that area, which is common in individuals experiencing anxiety.

It's also important to consider that the autonomic nervous system regulates involuntary bodily functions, including heart rate and breathing. Dysautonomia can lead to symptoms such as palpitations, shortness of breath, and chest discomfort, particularly during periods of stress or anxiety. In your case, the fact that your symptoms have persisted despite normal cardiac evaluations suggests that they may not be directly related to a heart condition.

However, it is crucial to remain vigilant. If you experience any of the following symptoms, you should seek immediate medical attention:
1. Severe Chest Pain: If the pain becomes intense or feels like pressure or squeezing.

2. Radiating Pain: Pain that spreads to your arms, neck, jaw, or back.

3. Shortness of Breath: If you experience significant difficulty breathing or feel like you cannot catch your breath.

4. Sweating: Unexplained sweating, especially if accompanied by other symptoms.

5. Dizziness or Lightheadedness: If you feel faint or lose consciousness.

If your symptoms continue or worsen, it would be prudent to follow up with a cardiologist for further evaluation. This may include additional tests such as a stress test or echocardiogram to rule out any underlying cardiac issues that may not have been detected in your initial evaluations.

In the meantime, managing anxiety through relaxation techniques, mindfulness, or cognitive behavioral therapy can be beneficial. Regular physical activity, a balanced diet, and adequate sleep can also help improve your overall well-being and reduce anxiety symptoms.

In summary, while your symptoms may be more indicative of anxiety or dysautonomia, it is essential to monitor your condition closely. If you have any doubts or if your symptoms change, do not hesitate to seek further medical advice. Your health and peace of mind are paramount, and staying proactive about your symptoms is the best approach.
