Hello
As you mentioned that you didn't having asthma because there is no any symptoms like wheezing or breathlessness . But there is cough from months, nasal drip ( very irritating ) ,
sore throat (as throat is not clear). You also mentioned that clear fluid or mucus come out with cough . I want to tell you one thing that asthma is not a disease but a symptom .
Post nasal drip , cough , mucus, sore throat all are an indication of allergy . These symptoms may be due to
sinusitis accompanied by allergic
bronchitis . When such type of patient visit in my clinic I advise them to take monteleukast+ bambuterole combination pack once in the night till complete relief. It might also help to take
dextromethorphan +ambrozol+chlorapheniramine maleat syrup .
I also advise to take dextromehophan lonzes for local soothing of throat.
Since these are prescription drugs , so get the help of a physician.
Avoid contact with hay, fine dusting powder, mold , pollen , smoking ( smokes ) , humidity , sudden fall & rise of temperature.
Hot coffee , steam inhalation also provide relief.
Good luck.
