Determine the time pattern of symptoms and whether symptoms occur at a consistent level throughout the year (ie, perennial rhinitis), only occur in specific seasons (ie, seasonal rhinitis), or a combination of the two. Determine whether the symptoms are present all day or only at specific times during the day. This information can help suggest the diagnosis and determine possible triggers.
