Stress-Related Hives: What to Know

Hives can be pink, red, or close to the surrounding skin. Individual welts may vary in size, join together, appear elsewhere, and disappear while new ones form. Itching is common, and rubbing or heat may make symptoms more troublesome. Stress can be one trigger, but foods, medicines, infections, pressure, temperature, and unknown factors can also be involved.

Deeper swelling of the lips, eyelids, hands, or throat is called angioedema and needs special attention. A rash that remains fixed, bruises, blisters, or hurts may not be typical hives.

Move to a cool environment, wear loose clothing, and use a cool compress rather than scratching. Avoid known triggers when possible and keep a record of foods, medicines, illness, heat, exercise, pressure, and stress before episodes. A pharmacist or clinician can advise whether an oral antihistamine is suitable, considering your age, pregnancy, health conditions, and other medicines.

Call emergency services immediately for swelling of the tongue or throat, trouble breathing, wheezing, difficulty swallowing, faintness, or sudden severe dizziness. Seek medical review for repeated hives, extensive swelling, hives after a new medicine, or a rash that lasts unusually long or develops bruising, pain, fever, or blistering.

Could these welts be hives or another rash? What triggers should I track, and which antihistamine is safe for me? What symptoms mean I need emergency help?
