If a patient has symptoms of undershirt pain, it is important to identify the primary cause and choose the right medication according to the primary cause in order to achieve the best treatment effect. For example, if the vest pain is caused by unstable angina of coronary atherosclerotic heart disease, you should take nitrate drugs, such as sublingual nitroglycerin, or isosorbide mononitrate, both of which can dilate coronary arteries and relieve unstable angina. If the undershirt pain is caused by a serious infection, such as a large area of pneumonia, or pleural effusion or pleurisy due to infection, anti-inflammatory drugs such as cephalosporin, ofloxacin, azithromycin must be taken to relieve the pain and play an anti-inflammatory role. If the patient is also accompanied by high fever, you can take certain non-steroidal anti-inflammatory drugs, which have the effect of relieving pain and reducing fever. No matter what the cause is, the cause of the undershirt pain must be identified, and then choose the relative drugs, so that the effect is better.
