The general symptoms of rhinitis are congestion, runny nose, and post-nasal drip, in which mucous drips into the throat from the back of the nasal passage, especially when lying on the back. Symptoms may vary depending on the cause of rhinitis. Symptoms of influenza and sinusitis must also be differentiated from allergies and colds. 

Symptoms of Allergic Rhinitis:

Symptoms of allergic rhinitis include frequent or repetitive sneezing, a runny or congested nose, and itching in the nose, eyes, throat, or roof of the mouth. People with allergic rhinitis may also have plugged ears, a decreased sense of smell, postnasal drip, or sinus headaches. Severe allergies can lead to dark circles under the eye; the lower eyelid may be puffy and lined with creases. Children may push their nose upward with the palm of their hand or twitch their nose rabbit-like to clear obstruction. 

Symptoms of Other Forms of Rhinitis:

Symptoms of vasomotor rhinitis are similar to most of those caused by allergies. Usually, however, they are more severe and occur predominantly on one side of the nose. In children, foreign objects pushed into the nose that are left in place may eventually cause infection and nasal discharge, usually in one side of the nose, which may be yellow or green and foul smelling.
