I have been suffering from cold, runny nose and cough repeatedly for about one month. Now the cough has become severe, especially at night, and it disturbs my sleep. I cough up sputum and I also hear a wheezing sound from my chest while breathing. There is chest congestion and heaviness. I do not have fever currently and there is no blood in sputum. I have not noticed any weight loss or night sweats. sometimes i took Mucinac 600 mg for mucus. Please advise whether this could be chronic bronchitis or asthma, and whether I need an inhaler, further medicines, or tests like spirometry.
