If a patient is diagnosed with myocarditis, especially viral myocarditis, and experiences chest pain, some analgesic medications can be used, particularly non-steroidal anti-inflammatory drugs (NSAIDs). If the patient has infective endocarditis or other forms of myocarditis, it is not recommended to use pain-relieving medications due to individual differences, as this may exacerbate symptoms and mask the true condition. For general cases of myocarditis, it is sufficient to use some common NSAIDs. However, it is still important to actively treat the primary disease, control the patient's symptoms, and initially use antiviral medications predominantly, which can also alleviate symptoms. Regular echocardiogram reviews to monitor changes are also necessary.
