The intermittent and sudden pain in the chest is caused by two main diseases. One, mainly myocardial infarction, may lead to sudden colic in the chest, which lasts from a few seconds to tens of seconds and will not last more than a minute. At this time, patients must go to the hospital for detailed related examinations, such as electrocardiogram or cardiac ultrasound, which can clarify this disease and must be actively treated symptomatically to avoid serious sequelae. Second, it may be caused by intercostal neuralgia in the chest. After the injury of the intercostal nerve in the chest, it will cause sudden colic pain, and in this case it will also last for more than a few minutes, and it is also necessary to go to the hospital for relevant examinations, such as an examination of the intercostal nerve, which can clarify the diagnosis. It is recommended that patients must undergo symptomatic treatment to avoid causing intercostal neuralgia to affect their normal life.
