What will i do if i have a on and off itchy throat that makes me cough hard without a pleghm ?

? Allergy: Affecting your upper airway and can still cause cough, you might be having upper/lower airway chronic inflammation, certain environmental triggers would stimulate your symptoms. See an ENT or an Allergist if you have one around, meanwhile, salt water gargles, saline nasal wash if you have congestion, and may be OTC less sedating antihistaminic, as loratadine, as needed would help, good luck
