[|AI|]  Hello are having cough for 3 months, got relief after medicine, recurs. Such type of recurring cough with impact on voice may be due to these possibilities, these include:1 Allergic bronchitis, diagnosis can be confirmed by physical examination by a physician. In this type of cough usually patient come in contact with some allergen like, dust, mite, mold, fine dusting powder, hay, fodder, smoke. These allergen produces antigen, antibody reaction and causes bronchoconstriction which produces cough as well as laryngeal irritation produces bad effect on vocal cord (voice).2 Asthmatic allergic bronchitis .3 Laryngeal tuberculosis, diagnosis can be confirmed by laryngoscope examination. In my opinion consult a pulmonologist and get his opinion. Good luck.
