Stabbing pain under the right chest is within the differential diagnosis of chest pain, and it is necessary to identify whether it is male or female. If it is male with stabbing pain under the right chest, it is necessary to see whether it is high-risk chest pain, moderate-risk chest pain, or mild chest pain. High-risk chest pain in the right chest in men can be right-sided tension pneumothorax, acute pulmonary embolism, right-sided tear of aortic coarctation or acute myocardial infarction, which usually do not have a high incidence but have a high mortality rate and require immediate hospitalization. Peripheral chest pain in men can include right-sided pleural effusion, right pneumonia, acute myocardial ischemia, and mild chest pain below the right side of the chest can include right-sided costochondritis, right-sided osteitis, and herpes zoster of the right chest wall. Diseases of the abdomen can also have a tingling sensation below the chest, but it is not common. Those with right-sided onset such as cholecystitis and peritonitis can also have a tingling sensation below the chest. For the tingling pain under the right side of the chest that is common in women, in addition to the above-mentioned diseases in men, breast diseases such as lobular hyperplasia, acute right-sided mastitis and breast tumors should also be considered.
