Chest Pain Near the Armpit: When to Seek Further Evaluation - Cardiology

Share to:

Sharp pain or electric shock sensation near the left chest close to the armpit?


Hello doctor, I am 32 years old, with a height of 175 cm and a weight of 72 kg.
There is a family history of hypertension.
I have a smoking history of about 5-6 years (I have quit).
About a year ago, I started experiencing sharp pain in the left side of my chest near the armpit.
Since then, I have quit smoking, and my condition has improved, but in the past few days, the pain has recurred.
The pain lasts for one to two seconds, but I feel that the frequency of occurrence has increased.
Yesterday, I had a chest X-ray and a standard electrocardiogram (ECG), and the doctor said everything was normal.
However, there may be arrhythmia, and I have been scheduled for a 24-hour Holter monitor and prescribed Inderal.
Aside from the sharp pain, I feel fatigued, but I currently do not have symptoms such as shortness of breath, chest tightness, or cold sweats.
I would like to know if I should get other tests done or wait for the Holter monitor results (the appointment is in nine days, but the symptoms seem to be becoming more frequent).

Hello, please remain calm.
The sharp pain in the left chest area near the armpit is more likely related to muscle or nerve issues rather than the heart, which would not typically present pain this far out.
You can take some B vitamins or acetaminophen and monitor your symptoms.
Take care, and this is a message from Changhua Hospital.

More Info


Chest pain, especially when localized near the armpit, can be concerning, particularly in someone with a family history of hypertension and a history of smoking. Given your symptoms and the fact that you have experienced intermittent pain for over a year, it is essential to approach this situation with caution.

Firstly, it's important to understand that chest pain can arise from various causes, including musculoskeletal issues, gastrointestinal problems, and cardiac conditions. The pain you describe as "sharp" and occurring for a few seconds could potentially be related to muscle strain or nerve irritation, especially if it is localized to the area near the armpit. However, given your age and risk factors, it is prudent to rule out any cardiac issues.

The fact that you have undergone an X-ray and a standard electrocardiogram (ECG) with normal results is reassuring. However, the mention of potential arrhythmia and the decision to conduct a 24-hour Holter monitor test indicates that your healthcare provider is taking your symptoms seriously. This test will help identify any irregular heart rhythms that may not have been captured during the standard ECG.

While you wait for the Holter monitor results, it is crucial to monitor your symptoms closely. If you experience any new or worsening symptoms, such as:
- Increased frequency or intensity of chest pain
- Shortness of breath
- Dizziness or lightheadedness
- Cold sweats
- Nausea
You should seek immediate medical attention. These symptoms could indicate a more serious condition that requires urgent evaluation.

In addition to the cardiac evaluation, consider discussing with your physician the possibility of other diagnostic tests that could provide further insight into your symptoms. These might include:
1. Echocardiogram: This ultrasound of the heart can assess its structure and function, helping to identify any abnormalities that may not be evident on an ECG.

2. Stress Test: This test evaluates how your heart performs under physical stress and can help identify issues that may not be apparent at rest.

3. Chest CT Scan: If there is concern about pulmonary issues or vascular problems, a CT scan can provide detailed images of the chest.

4. Blood Tests: Certain markers in the blood can indicate heart muscle damage or other underlying conditions.

Given your history of smoking, it's also essential to consider the long-term effects of tobacco use on your cardiovascular health. Smoking is a significant risk factor for heart disease, and even after quitting, the body may take time to recover from its effects.

Lastly, while waiting for your tests, it may be beneficial to adopt lifestyle changes that can support your cardiovascular health. This includes maintaining a balanced diet, engaging in regular physical activity (as tolerated), managing stress, and ensuring adequate sleep.

In conclusion, while your initial tests have returned normal results, the recurrence and frequency of your symptoms warrant further investigation. It is advisable to keep an open line of communication with your healthcare provider, report any changes in your condition, and follow through with the planned cardiac evaluations. Your health and well-being are paramount, and being proactive in addressing these symptoms is a crucial step in ensuring your safety.
