The left chest is where the heart is located and is very important to the human body. When people experience left chest pain, they always simply think that it is caused by pleurisy. In fact, we cannot simply draw a conclusion about left chest pain. There are many diseases that can cause chest pain. So what causes left chest pain? What other diseases may cause chest pain in the early stages of the disease? Below we will give you a detailed introduction to the causes of left chest pain.

What are the causes of left chest pain? 1. Chest pain caused by chest wall disease: It is mainly caused by lesions of the chest wall muscles, ribs or intercostal nerves. The main feature is that the pain is often fixed at the lesion site, and there are many obvious tenderness points locally. For example: (1) Intercostal neuralgia, which is a tingling pain along the intercostal nerves and is aggravated by coughing and breathing.

(2) Chest pain caused by rib fracture, with an obvious history of injury or long-term severe coughing. There is obvious tenderness in the painful area, which is more obvious when squeezed.

(3) Chest pain caused by herpes zoster in the chest and abdomen may cause blisters to appear locally, and the pain is generally not closely related to coughing or breathing.

2. Chest pain caused by lesions of the trachea, bronchi, lungs and pleura: The main feature is that the pain is often related to breathing and coughing. For example, the chest pain of spontaneous pneumothorax occurs suddenly, accompanied by difficulty breathing, coughing, shortness of breath, and even serious conditions such as cyanosis and shock. In pleurisy the pain is stabbing, most noticeable in the ribs where the chest expands the most. (Chest pain in trachea and bronchitis is significantly aggravated when coughing and breathing, and is accompanied by a burning sensation in the chest. In lung diseases such as pulmonary infarction, the pain is mostly confined to the affected area and may feel like a knife cutting. It will be aggravated when breathing, coughing, and moving.

3. Chest pain caused by the circulatory system: common diseases include coronary heart disease, pericarditis, etc. The characteristics of angina pectoris attacks are a feeling of strangulation, pressure or fear in the left anterior chest or behind the sternum. The attack usually lasts about 30 seconds and can be relieved by taking coronary vasodilators. In addition to the above symptoms, chest pain caused by myocardial infarction can also radiate to the left shoulder, inner side of the left arm, and sometimes to the chin, neck, and even upper abdomen. The pain is tight and severe, lasting for more than 30 minutes. Taking coronary vasodilation drugs has no significant effect. At the same time, symptoms such as arrhythmia may occur.
