Hi. i have shortness of breath and sharp pain on my left feeling abit of flu but nothing major?

Shortness of breath: I believe that true shortness of breath is a major symptom. When combined with sharp chest pains, there is concern for such conditions as pleurisy, pneumonia,pulmonary embolism,pneumothorax, pericarditis. Cough and fever would favor pneumonia. Be sure to notify your physician if symptoms persist or worsen especially if covid exposure is a possibility.
