Pain in the lower left chest?


Hello, doctor.
Recently, I've been experiencing sudden sharp pains on the left side of my chest that radiate to the lower part of my left chest.
Sometimes the pain lasts only a few seconds, while other times it can last for 3 to 5 minutes (and sometimes pressing on it causes pain).
I would like to know which specialty I should consult for an examination.
A while ago, I went to the emergency room due to chest tightness and saw a cardiologist, but the doctor said my heart tests were normal.
However, recently, I've been having these sudden pains in the lower left chest.
Could this possibly be caused by gastroesophageal reflux?

Hello, gastroesophageal reflux typically causes pain in the upper abdomen rather than the left chest.
I'm not sure if your pain worsens with inhalation or certain specific movements.
Based on your description, it seems more similar to pleurisy, costochondritis, or a muscle strain.
I recommend applying heat and getting plenty of rest.
If the pain persists, you may consider consulting a pulmonologist.
Thank you for your question.

Left chest pain can be a concerning symptom, and understanding its potential causes is crucial for determining the appropriate course of action. Based on your description, it seems that you are experiencing sudden, sharp pains on the left side of your chest that can last from a few seconds to several minutes. You also mentioned that pressing on the area can sometimes elicit pain. Given that you have already consulted a cardiologist and received a clean bill of health regarding your heart, it is important to consider other potential causes.

One common cause of left-sided chest pain is musculoskeletal issues. This can include muscle strain, costochondritis (inflammation of the cartilage connecting the ribs to the sternum), or even a pinched nerve in the neck or upper back. These conditions can lead to localized pain that may worsen with certain movements or pressure. If the pain is reproducible with palpation, it is more likely to be musculoskeletal in nature.

Another possibility is gastroesophageal reflux disease (GERD), which can cause chest pain that mimics cardiac pain. GERD occurs when stomach acid flows back into the esophagus, leading to symptoms such as heartburn, regurgitation, and sometimes chest discomfort. If you notice that your symptoms worsen after eating or when lying down, this could indicate a connection to GERD.

Anxiety and stress can also manifest as chest pain. Panic attacks, for example, can lead to sharp, sudden pain in the chest, often accompanied by other symptoms such as shortness of breath, palpitations, and a feeling of impending doom. If you have been under increased stress or anxiety, this could be a contributing factor.

Given your history of chest discomfort and the fact that you have already ruled out cardiac issues, it may be beneficial to consult with a gastroenterologist to explore the possibility of GERD or other gastrointestinal issues. They may recommend lifestyle modifications, dietary changes, or medications to help manage your symptoms.

Additionally, if the pain persists or worsens, or if you experience any new symptoms such as shortness of breath, dizziness, or radiating pain to the arm or jaw, it is essential to seek immediate medical attention. While your previous heart evaluations were normal, it is always better to err on the side of caution when it comes to chest pain.

In summary, while your left chest pain may not be related to your heart, it is important to consider other potential causes such as musculoskeletal issues, GERD, or anxiety. Consulting with a gastroenterologist could provide further insights, and if symptoms persist or worsen, do not hesitate to seek immediate medical care. Your health and peace of mind are paramount, so addressing these symptoms with the appropriate specialist is a wise decision.
