Occasional stabbing pain in the chest, if the frequency of stabbing pain is not particularly frequent, it is recommended to first check the electrocardiogram to see if there is local ischemia. Sometimes tingling is a sign of ischemia in the heart itself, and sometimes it is a sign of lesions in the lungs. The main tests to be done are the following: electrocardiogram; cardiac ultrasound; T or X-ray of the lungs to determine; angiography to be done. If the pain is simple and occasional, you can observe if it is accompanied by symptoms such as stuffiness and swelling of the chest and general sleepiness and discomfort, so that the cause can be found, diagnosed and treated. If there is no particular problem with the heart and lungs, and there are several stabbing pains, it is necessary to consider whether there is myofascial inflammation or costochondritis in the anterior thoracic region.
