Beyond Sneezing: Lesser Known Signs of Allergies

Beyond Sneezing: Lesser Known Signs of Allergies

It can be hard to tell if you’re getting sick or dealing with seasonal allergies during cold and flu season, as both can cause a number of symptoms that mimic one another. If you’re sneezing, allergies are likely the first thing to come to mind, but there are other symptoms you may be overlooking. 

At Dallas Family Medical & Aesthetics, family medicine physician Julie Reihsen, MD, can you help you determine if your symptoms are related to allergies, and get them under control if you do. 

Brain fog

Trouble concentrating or a feeling of brain fog is a less commonly known symptom linked to allergies. Uncontrolled allergies cause ongoing inflammation that can leave you feeling hazy. Once the cycle starts, it’s usually a downward spiral if left untreated. 

Having uncontrolled allergies can make it difficult to concentrate at work or school, and negatively impact your daily life. 

Nasal  congestion

Although nasal congestion is often linked with colds, you might be surprised to know that allergies could be behind your stuffy nose instead. Allergies can irritate the sensitive lining of your nose, leading to a stuffy or runny nose. Rather than suffer, you may be able to take allergy medications such as decongestants that can quickly soothe the lining of your nose and reduce congestion.

Itchy, watery eyes

Allergies can cause your eyes to become itchy and irritated, which can lead to excessive watering. This can cause you to rub your eyes, making your symptoms worse. Eye drops can help to treat your allergies and alleviate your symptoms.

Feeling tired 

Seasonal allergies can leave you feeling run-down and unwell, similar to when you have a cold or flu. But, symptoms like fever and severe aches are a clue that you’re likely dealing with a cold or flu. Allergies do not cause fever or severe aches. 


Coughing can be caused by many things, such as allergies, a cold, or the flu. While having a cold or flu often causes coughing as your body fights a virus, allergies commonly cause coughs because they increase mucus production and postnasal drip.

Itching and swelling

Hives are itchy, raised welts that are often part of an allergic response, either due to ingesting an irritant or making skin contact with one. Sometimes, allergies can also leave you feeling itchy in general, or cause swelling of a body part such as your lips, hands, or face.

If you suddenly notice a change in your appearance, it might be a sign of a severe allergic response. Similarly, if your allergies are making it hard to breathe, it’s important to see a doctor right away.

If you’re experiencing any of the above symptoms, you might be wondering whether it’s a sign of allergies, a cold, or the flu.
