I have had pnd for the last six months, at first the doctor told me it was fungal infection and I was on treatment for one months which never helped. Then the doctor told me it was chronic rhinitis, I have been given all types of medicine, sprays which sometimes causes me swelling of the neck but nothing changes. I don't have any other symptom, not headache not nosal congestion not anything else apart from postnasal drip. What do I do about it coz its so irritating
