3 weeks into Covid, elderly, asthma, breathing issues, panic

I am 69 years old have had severe seasonal nasal allergies and bronchial asthma since I was 10 years old
Past couple of years asthma better but nasal allergies worse this past summer very bad nothing helps but usually after first frost I feel ok until allergies start again in spring
Not this year stuffy nose sob see pulmonary dr saw ent predisone antibiotics nothing helped 3 weeks ago had crushing pain in my chest went to urgent care for a ekg they sent me to the hospital
Where they did a complete check up of my heart lungs everything fine as I was getting ready to leave 5 hours later the nurses comes in and tells me I have covid I was schocked went home they put me on paxlovid but had to stop mt metoprolol while on it did not agree with me after 3 days had to stop it go back on metoprolol well since then it’s been a nightmare primary pulmonary not always available in person going to different urgent cares because of the same stuffy nose and short of breath I had before covid one pa this at urgent care thinks it’s because I still have a infection or bronchitis that started before covid put me on a antibiotic another urgent care said don’t take the the antibiotic but my pulmonary said take it I got a nebulizer yesterday even though I never used one at home afraid to use it after all this confusion the moral of the story is that I would like to know how many other people are still having stuffy nose or breathing issues and for how long
