Man's natural tendency is to assume that there is no severe problem and ignore the symptoms. Many patients have met the doctor about 24 to 48 hours, some even three to four days, after the onset of chest pain. They said, "I just thought it was just gastric pain and took antacid, and it became fine." But actually, that first incident of chest pain itself would have been the first attack, and a much better treatment could have been given if the patient had presented earlier. Many patients even die when they visit the doctor and start the treatment.

These days we have been coming across many patients with heart attacks. Obviously, the main reason for this is the bad lifestyle and work culture where there is no scope or time for physical exercise. Even the diet of people is not healthy these days. This has resulted in a significant increase in the incidence of heart attacks. This article is not about how to change lifestyle or diet. It is about how to recognize or what to do when there is chest pain.

What Are the Causes of Left-Sided Chest Pain?

1. Heartburn and Acid reflux:

When the digestive acid present in the stomach moves upward into the esophagus, it is called acid reflux. Reflux of stomach contents can happen after eating, lying down, or waking up. As a result of this, heartburn occurs. This is because the esophagus (food pipe) has a mucosal lining that gets irritated by the stomach's acidic contents.

Heartburn is a chest pain that is most commonly accompanied by other symptoms like:

  • Sour and acidic taste.

  • Burning sensation in the chest or upper abdomen.

  • Reflux of the contents to the throat.

In some cases, this can turn into a more serious condition called gastroesophageal reflux disease (GERD). The below symptoms will be seen in addition to the chest pain in GERD:

  • Difficulty in swallowing.

  • Sore throat.

  • Persistent dry cough.

2. Esophageal Conditions:

Conditions affecting the esophagus can also bring about left-sided chest pain.

The following are the esophageal conditions:

  • Esophagitis - As the name suggests, it is an inflammatory condition of the esophagus. It can be distinguished from cardiac causes with the help of the below symptoms:

    • Blood in vomit.

    • Blood in stools.

  • Esophageal Muscle Spasms - Spasms of the muscles of the food pipe can also cause left-sided chest pain. Distinguishing it from cardiac causes is problematic since, in most cases, it often resembles the pain caused by a heart attack. Seek the help of a healthcare provider immediately to rule out the cardiac causes.

However, since most of the accompanying symptoms of left-sided chest pain are almost similar, taking a chance is unacceptable. Whatever be the intensity or duration of pain, reaching out to a healthcare provider is always recommended. This is because distinguishing between the pain and identifying the causes is not feasible.

So, everyone should remember this. "NEVER NEGLECT A CHEST PAIN. " More so if it is:

  • Squeezing type of pain or heaviness in the chest.

  • Radiation of pain to the left arm or neck.

  • Associated with sweating or dizziness.

Even if these factors are not there, it is advisable to consult a doctor if you experience chest pain (even at midnight).

But again, do not just sit at home after taking the pill; go to the doctor as soon as possible.


Mastering the medical diagnosis is not a cakewalk for the general public. Therefore, sticking to the physician's advice is only recommended, especially when it concerns life. Be it mild or severe, be it for a short-term or a long-term, be it any time of the day, seek the help of a healthcare provider to rule out the severe causes or get prompt treatment.
