Sneezing, a possible symptom of allergies

Allergy Symptoms

To understand your allergy, you need to know when your allergies are troubling you. To do this, you have to recognize all potential allergy symptoms. Some of the most common allergy symptoms to look out for are:

Itchy eyes caused by allergens

Itchy, watery eyes

Airborne allergens come into direct contact with your eyes.

Runny nose

Allergens enter your nose and the membranes become irritated and swollen, produce fluid that’s thin and clear.

Sneezing

Sneezing is a reaction to histamine, related to the itchiness and swelling inside the delicate membranes in your nose and throat.

Sore nose caused by allergens

Scratchy or itchy nose and/or throat.

You can even suffer from itchy ears and an itchy roof of your mouth, all this discomfort can drain your energy and disrupt your day.

Sinus congestion

Sinuses become swollen and blocked. Allergy sufferers have described it as a tight or heavy sensation in the head, cheeks or forehead, a feeling of being “blocked,” “stuffed up,” or as if they’re “underwater.”

Skin reactions

Apart from classic hay fever symptoms like sneezing, blocked or running nose, tiredness and itchy eyes, allergies can also appear in other forms. For instance, if you’re allergic to nickel in jewelry, you may develop contact dermatitis: redness, scaling or a rash. Other allergies, including many in the list above, can appear as urticaria or hives: weals (raised white circles) or flares (red, flattened blobs) on your skin. In chronic cases, the rash and itchiness can cause sleepless nights.

Skin rash caused by an allergic reaction

If you are suffering from any of the above symptoms, you could have allergy. To find out what you may be allergic to visit our allergy types page, or if you already know what you are allergic to, find out which products can help you manage your allergy symptoms here.
