Little bit of cough congestion in throat

I tested +ve for Covid on april 3. As of now all symptoms are gone after covid medication. Only coughing was there, took Grillinctus which relieved very much now I cough only once or twice that too when I am talking so much or laugh hard. Now only problem is that I feel there is little bit of congestion below Adam's apple in throat. No fever, no pain, no weakness, SpO2 96 to 99% through out. After steam and gargle congestion get released but it builds up again. It was not the scenario before covid. Also weather has changed bit since a week (mostly cloudy and cool). Due to congestion I dont feel that my throat is clear. Please advise medication if any or is this normal. I dont feel any pain in chest, no problm in breathing when congestion gets released.
