Hello
You are having severe cough and cold ( for January i.e 8 months passed ) and taken antibiotics course as well as also taking grilintus, mucomelt tablets .
Since 8 months passed and still cough present ,may be due to these reasons , these include:
1 Asthmatic allergic
bronchitis , diagnosis can be confirmed by physical examination by a physician . Whistling sound ,
dry cough , breathlessness are the characteristic features of asthmatic allergic bronchitis .
2
Tuberculosis is another such cause of such severe cough . Diagnosis can be confirmed by X ray chest , blood for ESR , Montoux's test.
3 Asthma , this is most common cause . Due to mite , dust , smoking , pollen , hay , fodder , fine dusting powder there develop
bronchoconstriction and this produces dry cough .
Still I advise please
consult a PULMONOLOGIST and get his opinion .
