My husband is having cough from last 3 months. He is allergy to perfumes, dust. He was infected with covid since den he started getting sneeze in the morning. In the month of December as c weather was not good he started with cough with mucus. Sneeze also and runny nose. He took Montek LC, he was fine for a week. After 1 week sneeze stopped but cough started with white mucus. It's been 2.5 months he is having cough with white mucus and blocked nose. Started using foracort 200 inhaler and flomist nasal spray from last week. No changes noticed. No other symptoms other than cough, white mucus and blocked nose.
