Hello Thanks for the query. Let me explain about allergic bronchitis , very common complaint in children as well older one. Whistling sound during breathing, running nose, tears in eyes, itching over face and rubbing of eyes , snot from nose ( mucus), dry cough . All these above symptoms are very common in children and cause is only one . Asthmatic allergic bronchitis . Reason is bronchoconstriction . Mite , dust , pollen , hay , sudden rise and fall of temperature , fine dusting powder all are predisposing factors for asthmatic allergic bronchitis. Usually infection don t present . In such type of cases I only prescribe bronchodilator and antihistamine . I don t like to prescribe antibiotics ( if fever present I prescribe antibiotics ). Hope you got answer. Good luck. Dr. HET
