The top three triggers for allergic reactions are airborne allergens (pollen, dust mites, pet dander, and mold), specific foods (peanuts, tree nuts, milk, eggs, shellfish), and insect stings (bees, wasps). These allergens cause immune system overreactions, ranging from mild irritation to severe, life-threatening anaphylaxis.

What are common triggers of allergic reactions?

Common allergy triggers include:

• Airborne allergens, such as pollen, animal dander, dust mites and mold.
• Certain foods, especially peanuts, tree nuts, wheat, soy, fish, shellfish, eggs and milk.
• Insect stings, such as from a bee or wasp.
• Medicines, especially penicillin or penicillin-based antibiotics.

Can allergies cause bruising?

Yes, allergies can cause bruising, most commonly as "allergic shiners" (discoloration under the eyes from congestion) but also potentially from severe reactions like allergic vasculitis, which damages blood vessels, causing bruise-like spots, or from medications used for allergies that thin the skin. True bruising from trauma (a black eye) differs from allergic shiners, as shiners usually appear under both eyes due to pooled blood from congestion, not injury.

Can allergies cause ear pain?

Yes, allergies can absolutely cause ear pain, pressure, and fullness by triggering inflammation and mucus in the Eustachian tubes (connecting middle ear to throat), which blocks them, leads to fluid buildup, and can even result in infections or skin irritation, causing pain, muffled hearing, or a feeling of being underwater.
