Hi i had a sinusitis a week ago. it since have cleared up. but i feel tired quick and shortness of breath, also feel light headed. please advise ?

Fatigue/SOB ?'s: In today's pandemic, fatique, shortness of breath, dizzyness can be symptoms of Covid virus. Get a PCR test for Covid, and quarantine yourself and any close contacts for at least 10 days, even if the test is negative. Post-Covid shortness of breath can last for a week or more, but if symptoms worsen, go to an ED for treatment.
