Sign #1: The Allergic Salute

You vacuum with a HEPA filter. You stay indoors when the pollen count is high. You take medications as directed. But do you really have your allergy symptoms under control? If you're constantly doing the "allergic salute," the answer is probably no. This gesture -- a swipe at the tip of an itchy, runny nose -- is especially common in children

Sign #2: Raccoon Eyes

Dark circles under watery eyes are another sign of allergies. You can get circles when you're always rubbing itchy eyes. Fortunately, itching, tearing, sneezing, and a runny nose can all be relieved with antihistamines. If you already take this type of medication, check with your doctor about changing your dose or when you take it.

Sign #3: Chronic Congestion

A stuffy nose usually lasts a week or two when a cold or flu is to blame. If congestion goes on and on, allergies are a more likely suspect. During an allergic reaction, the lining of your nasal passages may swell and produce extra mucus. This can cause sinus pressure and headaches. Decongestants can give you short-term relief. For a long-term plan of action, consider seeing an allergist.

Sign #4: Wheezing

Wheezing is often linked with asthma, but it can also be a sign of a serious allergic reaction. The characteristic whistling sound happens when air passes through narrowed airways. In severe cases, wheezing needs emergency care. You should be checked by your doctor if you have wheezing related to allergies.

Sign #5: Itchy Skin

Itching may just be a sign of dry skin. But when it doesn't stop, and especially when it comes with a rash, eczema may be to blame. Eczema is a type of skin reaction that's common in people with allergies. Triggers may include soap or detergent, pet dander, and rough materials. Antihistamines, moisturizers, and hydrocortisone cream can help soothe flares. For severe cases, prescription medications are available.

Sign #6: Hives

Hives are hard to miss. These pale red welts tend to itch, and they can last from several hours to several days. Often, they're caused by an allergic reaction to some type of food, medication, or insect sting. Antihistamines usually give you immediate relief. Steroids may be needed in some cases. But the best solution is to find and avoid the trigger.

Sign #7: Insomnia

Itching, congestion, post-nasal drip, sinus pain -- and other allergy-related symptoms can be tough on sleep. Symptoms like coughing or wheezing may wake you up, and a stuffed nose may make it hard to fall asleep. Some allergy drugs can also disrupt a good night's sleep. Trouble sleeping is one sign that it may be time to ask your doctor about changing how you treat your allergies.

Sign #8: Trouble Concentrating

You may find it hard to concentrate when your eyes are tearing, your nose is dripping, and you've been up all night. Plus, some over-the-counter antihistamines may make you feel foggy. If you find your work, home life, or relationships are suffering because of allergies, tell your doctor. It may be time to discuss your treatment options.

Sign #9: Fatigue

Allergies can deal a triple-whammy to your energy level. First, your symptoms can affect the quality of your sleep. Second, allergies cause your immune system to constantly overreact, which can cause fatigue. Third, some antihistamines cause drowsiness. Some newer antihistamines or other medications may be less likely to cause drowsiness. Ask your pharmacist for help.

Sign #10: Depression

Do you feel blue whenever your allergies flare? Some research points to a connection between allergies and mood changes. The National Institute of Mental Health is studying the link between seasonal allergies and depression. Although we can't prove that allergies cause people to feel depressed, there are effective treatments for depression. Be sure to let your doctor know if you feel down.
