Chest Pain: Why we should be concerned

The body’s left side is home to a number of important internal organs which include the large intestine, pancreas, stomach, spleen, heart, and left kidney. People who may have some form of pain on the left side of the body may be worried and rightfully so since such pain or sensation may be an indication of a possibly simple or severe medical condition. 

Chest Pains Left Side Under Breast and the Heart

Listed below are some of the possible causes of chest pain due to issues with the chest and the heart:

Heart Attack

People think of a heart attack when they feel pain in the left-center side of their bodies and rightfully so. This is because the heart is located on this side of the human body. Some of the other symptoms of a heart attack include pressure, tightness, or squeezing in the chest area. It must be noted though that these symptoms don’t show up at all times and it is possible that patients experiencing heart attacks may have no indication or pain at all. Some of the other symptoms of a heart attack include discomfort in the jaw, shoulder, fatigue, vomiting, nausea, and shortness of breath. Healthcare professionals may recommend that the patient undergo angioplasty which can help the blockage of a clogged artery. To keep the artery free of any blockage, a stent may be utilized. Prevention of a heart attack is for patients to simply shift into a diet that is healthier which means taking in more veggies, fruits, lean meats, and other whole-grain food items.


This medical condition affects the outside portion or membrane of the heart and results in inflammation of the said layer of the heart. The patient will experience pain once the membrane or the layer that is irritated rubs against the muscles of the heart itself. Pericarditis can be caused by a number of different factors and some can be prevented while some are inevitable. Patients may experience some type of pain that is stabbing which can become worse when the patient tries to swallow, cough, or lie down. The sensation can also be felt around the patient’s shoulder, neck, and back. Patients with pericarditis can also experience anxiety and tiredness. Treatment for pericarditis will involve the intake of pain-relievers, steroids, antibiotics, and anti-inflammatory medicines. Pericarditis should also be treated immediately and a healthy lifestyle should be observed to prevent being afflicted with the aforecited medical condition.

Precordial Catch Syndrome

This condition is more common in young adults and kids and occurs when chest wall nerve endings become irritated or pinched. Precordial Catch Syndrome can happen due to posture that is bad, a chest injury, or even a sudden spurt in growth. While the said medical condition may have similar symptoms to that of a heart attack, precordial catch syndrome will usually get better on its own. In fact, individuals will mostly outgrow the risk of such a condition when they reach their mid-20s. Some of the symptoms of Pericordial Catch Syndrome include pain that worsens with deep breathing, the onset of pain that is described as sudden, and pain on the left side of the chest that can be characterized as stabbing.

Chest Injuries

Injuries to the chest caused by a variety of different reasons can result in chest pain. Such activities include sports-related activities, vehicular accidents, and falls. Once these activities result in bruises or broken or cracked ribs, they can cause chest pain. Once such injuries happen to the left side of the body, serious consequences may be experienced as broken or cracked ribs can puncture vital organs such as the spleen and the liver. Some of the symptoms of a chest injury include pain when twisting the torso or the chest, pain when breathing deeply, and tenderness in the area of the injury.

Chest Pains Left Side Under Breast Related to the Digestive System

Listed below are some of the causes of chest pain relating to the digestive system:


Since the stomach is located in the upper portion of the body’s left side, it can cause chest pain once it becomes affected by certain health conditions such as when the stomach lining gets irritated or inflamed. These may be caused by a number of factors such as chronic alcohol intake, consumption of food items that are spicy, and the use of specific medications. Some of the symptoms of gastritis include pain in the left portion of the body, the fullness of the abdomen, vomiting, nausea,  and indigestion.


A condition caused by the inflammation of the pancreas, pancreatitis can incorrectly activate the enzymes meant for digestion resulting in irritation and inflammation. Some of the more common symptoms of pancreatitis include stools that are oily, fever, vomiting, nausea, pain in the upper abdominal area. Pancreatitis can be treated with surgical removal of the gallstones and certain medications can be given to the patient as well such as anti-nausea and pain relievers. A change in lifestyle may be needed to prevent pancreatitis which may include ceasing alcohol intake, smoking, and eating fatty food items.
