Hives are usually harmless, but when combined with breathing difficulty, they may signal a life-threatening allergic reaction called anaphylaxis.<\/p>\n
Warning signs include: shortness of breath, throat tightness, swelling of the face or tongue, rapid heartbeat, and dizziness.<\/p>\n
Common triggers include foods, insect stings, medications, latex, and allergens. Symptoms can escalate quickly and become dangerous.<\/p>\n
Seek emergency help immediately if hives occur with breathing problems and use an epinephrine injector if available.<\/p>\n
