Salam alaikum, Samad...Nose allergy is a problm that needs thorough structural examination of nose, including nasal endoscopy n if needed radiologic investigation like CT Scan of nose and paranasal sinuses. It also involves certain blood tests n skin prick test to evaluate allergy. Considering u r from other nation(i mean, distance barrier), i would advice that please visit personally any senior ENT surgeon near u, who also is an allergy specialist; so that all treatment can be done under one roof in your nation itself...Because this will be more convenient for u...Regards.
