[Concern] Dull pain in the left chest?


Recently, I have occasionally felt a tight sensation in the lower left side of my chest.
Given my age, I am unsure if I should be concerned.
Although this is a new symptom, it mostly occurs when I am lying down, so I initially thought it was due to poor posture and didn't pay much attention until tonight.
The weather was hot, so I took out my swimsuit and went swimming in the evening, followed by using the sauna and steam room.
After swimming a thousand meters, I rinsed off in hot water and changed before walking home.
On the way, I stopped at a 7-Eleven to buy a cheese and ham sandwich and a 330ml carbonated drink, eating while walking for about 20 minutes until I got home, where I immediately took a hot shower and towel-dried my hair.
After lying down, the symptoms suddenly appeared with a vengeance, more intense than before.
I felt a sharp pain at the lower edge of my left chest near the ribs, making it difficult to breathe.
I immediately sat up and took deep breaths, but it didn't help; lying down was uncomfortable as well.
After a while, when I lay completely flat, the symptoms mysteriously disappeared, leaving me feeling warm.
I then got up to handle some tasks.
About half an hour later, while sitting down to use the computer, I felt my heart racing, and an electronic blood pressure monitor showed normal blood pressure with a heart rate of 92.
The pain was noticeable but not unbearable, though it caused shortness of breath.
The pain was localized to a specific point that I could easily identify with my finger, rather than being diffuse.
My BMI is approximately 28, and my body fat is 38, so I have been trying to lose weight recently.
I am unsure if I should be worried.
Thank you for taking the time to read this lengthy message, and I appreciate any advice you can provide.
Have a good day!

When it comes to left chest pain, especially in the context of your recent experiences, it is crucial to approach the situation with caution. Your symptoms, which include a sharp pain in the left lower chest area, difficulty breathing, and a sensation of tightness, warrant careful consideration. While it is understandable to attribute these sensations to posture or physical activity, the nature of chest pain can often be indicative of various underlying conditions, some of which may require immediate medical attention.

Firstly, it is important to recognize that chest pain can arise from a variety of sources, including musculoskeletal issues, gastrointestinal problems, and cardiovascular concerns. Given your description of the pain being localized and sharp, it could potentially be related to musculoskeletal strain, especially if it occurs after physical activities such as swimming or lifting. However, the sudden onset of pain that is exacerbated by lying down and relieved by sitting up could also suggest a more serious condition.

One possibility is that you may be experiencing a form of costochondritis, which is inflammation of the cartilage connecting the ribs to the sternum. This condition can cause localized pain that may worsen with certain movements or positions. However, it is essential to differentiate this from more serious conditions such as angina or myocardial infarction (heart attack), particularly given your age and the presence of risk factors such as elevated body mass index (BMI) and body fat percentage.

The fact that you experienced difficulty breathing alongside the pain raises a red flag. While it is reassuring that your blood pressure was normal and your heart rate was not excessively elevated, the sensation of not being able to breathe properly can be concerning. It is important to consider the possibility of anxiety or panic attacks, which can mimic cardiac symptoms, but it is equally critical to rule out any cardiac issues.

In light of your symptoms and the context in which they occurred, it is advisable to seek medical attention, especially if the pain recurs or worsens. A healthcare provider may recommend diagnostic tests such as an electrocardiogram (ECG), chest X-ray, or echocardiogram to evaluate your heart's function and rule out any serious conditions. Additionally, blood tests may be performed to check for markers of cardiac stress or other underlying issues.

Furthermore, lifestyle modifications, including weight management, regular exercise, and a heart-healthy diet, can significantly impact your overall cardiovascular health. Given your current efforts to lose weight, it is essential to continue these practices while also being mindful of any symptoms that may arise during physical activity.

In conclusion, while your symptoms may be benign, the combination of localized chest pain, difficulty breathing, and the context of recent physical activity necessitates a thorough evaluation by a healthcare professional. It is always better to err on the side of caution when it comes to chest pain, as timely intervention can be crucial in preventing more serious complications. Please consider scheduling an appointment with your healthcare provider to discuss your symptoms in detail and receive appropriate care.
