Your doctor can often diagnose allergic rhinitis by asking you questions about your symptoms and past medical problems. Following are some questions he or she may ask:

• What are your allergy symptoms like? What is your main symptom? How much does it bother you? Is there anything that makes it worse?
• How old were you when you first had these symptoms?
• How often do you have allergy symptoms, and how long do your symptoms last?
• Do you have trouble sleeping or have you missed school or work because of your allergy symptoms?
• What time of year and what time of day do you have allergy symptoms?
• Does anyone else in your family have allergy problems, including allergic asthma?
• Do you have other medical conditions that are related to allergies, such as asthma, eczema, or rhinitis?
• Did you have allergies as a child?
• What medicines, including over-the-counter medicines and dietary supplements, are you taking now? Do these medicines help your allergy symptoms?
• Have you ever had surgery on your nose, throat, or ears?

Your doctor may also ask questions to help learn what might trigger your allergy.

• Where are your allergy symptoms worse? At home? At work? At school?
• Does your home ever feel damp or wet? What is the usual temperature in your home?
• Do you ever use air conditioners or humidifiers?
• Do you have carpeting in your bedroom?
• Do you have any indoor pets, such as a cat or a dog?
• Do you spend most of your time indoors or outdoors?
• Do you work with chemicals or other irritating substances?
• Do you or anyone in your household smoke?
