I have been coughing for almost 2 months. It's not chronic though. Mostly happens in Night and morning while brushing. Sometimes it happens while working in the afternoon. As I said, it's not chronic and mostly dry but sometimes I feel phlegm when I drink hot water. I feel phlegm moving down to my throat. It's not the first time. It happens every year. But it's most likely bit over one month but this time it's almost two months. Could anyone please guide me what's happening? Is it some kind of allergy or what? It happens only on winter. Like Oct, Nov, Dec, Jan. Thanks🙏
