I tested positive for covid last night for the first time and i am unsure what to do, its hard to breathe out of my nose and my chest feels tight?

Pl call your MD ASAP and discuss whether you should be seen or can be treated at home. Hope you do well

Infection with omicron subvariants is not serious at your age and usually mild in female population. You should buy a pulse oximeter for monitoring oxygen. You are safe if number stays above 92%, only call 911 if number drops below 90. Use nasacort or nasonex inhaler for nose congestion and take tylenol for sore throat. Paxlovid (anti covid-19 drug) is not indicated if you're otherwise healthy.
