A. recurring and non resolving cough and cold is commonly due to allergy and less likely due to infexction. can be due to either allergy or infection or both. along with cough and cold medicine nebulization will be required and your doctor will guide you regarding this. take a follow up with your doctor if txhe cough and cold is not improving with 3 days of medication . it is very important to give proper inhaler as well as proper method of nebulization for better recovery
