Answer

Other patients may describe year-round symptoms that do not appear to be associated with specific triggers. This could be consistent with nonallergic rhinitis, but perennial allergens, such as dust mite or animal exposure, should also be considered in this situation. With chronic exposure and chronic symptoms, the patient may not be able to associate symptoms with a particular trigger.
