Do you have to have runny nose, sneezing etc to have allergic rhinitis i don't have either except for a swollen turbinate & clear fluid in ears.

Rhinitis: Runny nose, sneezing/congestion are the cardinal symptoms of rhinitis, whether allergic or non-allergic. Swollen turbinates and clear fluid in ear (middle ears), are rather signs of inflamed nasal passages affecting middle ears drainage, yes you can have them without the classic symptoms in acute conditions, if long standing, better see an ENT for evaluation, good luck
