Light chest pain and fever flush mean what?

Need more info. There are many causes of chest pain, fever, and flushing. So more information is needed. Fever, of course, suggest some type of infections such as bronchitis or pnsumonia, but there is too little information here to make a diagnosis.
Depends. Could be upper respiratory infection. Could be heartburn. Could be pericarditis. Could be angina. Could be result of hormones (menopause). Could be result of hyperthyroidism. Could be anxiety. Could be result of undiagnosed pheochromocytoma. Depends.
