An important part of diagnosing allergies is a careful evaluation of your symptoms. Your doctor will ask you several questions to rule out other conditions that may cause allergy-like symptoms.

Questions Your Doctor May Ask

What type of symptoms do you have?
How long have you had these symptoms?
When symptoms occur, how long do they last?
Are your symptoms seasonal (come and go throughout the year) or do they last year-round?
Do your symptoms occur when you are outdoors or indoors, such as when you clean your house?
Do your symptoms get worse when you are around pets? Do you have any pets?
Do you smoke? Does anyone in your family smoke?
Are your symptoms interfering with your daily activities or interrupting your sleep?
What makes your symptoms better? What types of treatments have you tried? What allergy medication(s) are you taking now? Do these medications provide relief? Do they cause unwanted drowsiness?
What other medications are you taking, including prescription, over-the-counter, vitamins and herbal supplements?
What type of heating system do you have? Do you have central air conditioning?
Do you have any other health conditions, such as asthma or high blood pressure?
Are you having difficulty with your sense of smell or taste?
What makes your symptoms worse?
How much can you modify your lifestyle to reduce your exposure to these allergens?
Physical Examination

In addition to asking questions, your doctor will perform a complete physical exam. Your skin, eyes, nose, ears, and throat will be examined. Your doctor will look for inflammation (redness or swelling), drainage, or other signs of allergy symptoms.

Other tests may be performed -- based on your doctor's recommendations after the medical history and examination -- to determine which allergens are causing your symptoms. These may include a skin test or blood test.
