If you consult a good allergy or ENT doctor, they listen, see, test and prescribe some anti histamines or suggest surgery etc. without informing us the complete pros and cons of allergy and its treatment. They never tell exactly that allergy is not curable. They always find wrong with our nose! for surgery etc. and prescribe medicines whenever you visit them. I 've been suffering from allergic rhinisitis since childhood and undergone surgery also but stopped going to doctors now for this reason.(30 years experience!) For the last 30 years, no any doctor has suggested me for immunotherapy/ allergy is incurable etc. If I go to them they give antihistamine for a couple of weeks, and goes on like this (may be until death!)
