Hives (Urticaria) & Massage: Why to Avoid It

Do not massage hives. Urticaria involves mast cell degranulation → histamine release → vasodilation and fluid extravasation (wheals). Mechanical stimulation (massage) worsens:

• Itching and swelling (physical urticaria trigger).
• Spread of lesions (Koebner phenomenon).
• Potential systemic mediator release.

Instead: cool compresses, oral antihistamines (cetirizine, loratadine), avoid triggers, loose clothing. See a doctor if widespread, angioedema, or breathing difficulty.
