What is left-side chest pain?

As the name suggests, left side chest pain is a pressure-like feeling or pain on the left side of the chest. It can sometimes travel to the neck, into the jaw, the back, and even one or both arms. Left side chest pain may occur in many forms, ranging from a sharp stabbing pain to a dull ache. There can be a range of causes, and they can be of varying intensity, duration, and region of impact. Sometimes, it may be a result of an underlying problem associated with the lungs, heart, muscles, bones, or even the digestive system. Let’s understand its causes in detail.

Causes of Left Side Chest Pain

The causes of chest pain on the left side can be various, but most commonly due to issues arising in the heart, lungs, blood vessels, digestive system, or other areas.
