Chest tightness or chest pain?


Hello, Doctor.
In June, I noticed a feeling of tightness in my left chest that I experience every morning upon waking.
Compared to my right chest, the left side feels constricted and this sensation almost lasts the entire day.
The next morning, it feels the same, and sometimes I also experience slight sharp pain.
I went to see a cardiologist, who mentioned that my heart rate was too fast and diagnosed me with mild mitral valve prolapse, prescribing medication for me.
After taking the medication, I felt somewhat better and did not return for further visits.
However, recently, I have started to experience this persistent tightness in my left chest again.
A few days ago, I suddenly felt pain in my left arm for about half an hour.
I am unsure if this is related to the chest tightness.
Should I return for further examination, or could there be other issues? Thank you for your guidance, Doctor.

Hello, heart problems can indeed be associated with discomfort in the left arm; however, it is also possible that it is simply inflammation of the left arm.
It is essential to visit a cardiology clinic for further evaluation to confirm the diagnosis.
Thank you for your question.

It's understandable to feel concerned about persistent chest discomfort, especially when it has been ongoing and accompanied by other symptoms like arm pain. Chest discomfort can arise from various causes, some of which may be benign, while others could indicate a more serious condition. Given your history of mitral valve prolapse and the recent symptoms you've described, it's important to approach this situation with caution.

Firstly, the sensation of tightness or discomfort in the chest can be attributed to several factors, including anxiety, musculoskeletal issues, or gastrointestinal problems, but it can also be related to cardiac conditions. The fact that you have previously been diagnosed with mitral valve prolapse and experienced palpitations suggests that your heart may be involved. While many individuals with mitral valve prolapse lead normal lives without significant issues, it can sometimes lead to symptoms like chest pain or discomfort, especially during periods of stress or anxiety.

The sudden onset of left arm pain, particularly if it occurred alongside your chest discomfort, is noteworthy. In some cases, arm pain can be a sign of cardiac distress, especially if it is accompanied by other symptoms such as shortness of breath, sweating, or nausea. While it’s possible that the arm pain could be unrelated and due to muscle strain or another benign cause, it’s essential to take these symptoms seriously.

Given that your symptoms have recurred and you have experienced new symptoms, it would be prudent to seek medical attention again. A follow-up with your cardiologist or a visit to the emergency department may be warranted, especially if the discomfort worsens or if you experience additional symptoms. Your healthcare provider may recommend further testing, such as an electrocardiogram (ECG), echocardiogram, or stress testing, to evaluate your heart's function and rule out any significant issues.

Additionally, consider discussing your anxiety levels with your healthcare provider. Anxiety can exacerbate physical symptoms, including chest discomfort, and addressing any underlying anxiety may help alleviate some of your symptoms. Cognitive-behavioral therapy (CBT) or other forms of counseling can be beneficial in managing anxiety and its physical manifestations.

In summary, while your previous evaluations may have indicated that your heart is functioning well, the recurrence of chest discomfort and the new symptom of arm pain warrant further investigation. It’s always better to err on the side of caution when it comes to chest pain. Don’t hesitate to reach out to your healthcare provider for a thorough evaluation and to discuss your concerns. Your health and peace of mind are paramount, and seeking help is a proactive step towards ensuring your well-being.
