Chest Pain on Left Side

Last reviewed by Dr.Mary on August 1st, 2011.

Any chest pain on the left side can be alarming for almost everyone due to the fact that everyone immediately suspects heart problems with any chest pain. This is a normal reaction but it is not always correct. While the heart is in the left side of the chest, the nerves connected to the heart are in the center of the chest.


To put your mind at rest, if an individual is having a heart attack, he/she will probably have different symptoms than pain in the left side of the chest. The pain is not only in a different place – center of chest – but it feels more like a squeezing, heavy feeling instead of a sharp pain. Most of the time heart attacks feel like indigestion with other side effects also involved, such as breathlessness, sweat or even vomiting. The pain might also travel to the neck, jaw, arms, back or stomach. If these are your symptoms get medical assistance as quickly as possible.

Women could have pain in the breast for instance, breast pain several days before a period starts. Even things that are outside the chest for instance anxiety can cause chest symptoms. But it is important to work with a physician to come up with a reason for this discomfort
