Hello Since you are having asthmatic attacks and livolin rotacaps , provide some relief , but this time you are not getting relief . Also having cough ( dry in nature , as mentioned in the query) , dry cough is usually due to bronchoconstriction ( this is a characteristic feature of asthma ) . Recently also operated for thyroglossal cyst but this allergy may be due to dust , mite , fumes , sudden change in temperature , pests , pollen or mold . As these are certain predisposing factors for an asthmatic patient . When such case visit I prescribe them to take montelukast+bambuterol ( 10 mg each ) once or twice in day and my patient respond very well . Since this is a prescription drug so consult your doctor . However , hot coffee and steam inhalation also act as bronchodilator and provide relief in cough and asthma . Hope this will useful for you.
