I have been to the doctor last week because my chest had an burning sensation, i am a smoker yes. but had stuffy nose and some coughing, was on antibiotics since laat week monday and chest still feels tight, just scared it might be covid related?

Very possible : Certainly sounds like a viral bronchitis. COVID19 is another virus among many. Can’t tell without a nose or throat test. Need to confirm. You will (probably) get better but you’re a real risk to others around you

COVID 19: Agree with Dr. Lentnek. The only real way to determine if COVID 19 was the cause of symptoms or if you could have co-existing COVID 19 is via testing.
