My left back and chest often ache. How is this?

1. angina pectoris: it is characterized by paroxysmal chest squeezing pain, which may be accompanied by other symptoms. The pain is mainly located behind the sternum and can radiate to the precordial area and the left upper limb. It often occurs in labor or emotional excitement, and can occur once every few days for 3-5 minutes, or several times a day, and disappear after rest or use of nitrate preparation. This disease is more common in men, and patients are more than 40 years old. Fatigue, emotional excitement, satiety, cold, rainy weather and acute circulatory failure are common causes.

2. Intercostal neuralgia: It can be seen that the pain radiates in a semicircle from back to front along the corresponding intercostal space; Pain is a tingling or burning sensation. The pain increases when coughing, taking a deep breath or sneezing. Most of the pain occurs on one nerve on one side.

3. Lung diseases such as pneumonia and lung cancer.

I suggest you go to the hospital for a check-up, because it is likely to be angina pectoris.
