It's been one and half month after covid, I was recovered within 14 days but now from past 1 week I'm suffering from nasal congestion with runny nose and dry throat at night and then cough starts. Runny nose lasts for 2 hour and then I would be having problem in breathing due to congestion in nose. I would get some wheezing sound in night while sleeping. In morning I would be fine but in night it will start all of sudden. What would be issue and treatment for this.
