🌿 Overview
Nettle rash (urticaria from stinging nettles) occurs when contact with the nettle plant pricks tiny chemical irritants into the skin. The resulting raised, red welts are intensely itchy and burn, lasting a few hours before subsiding. New lesions may appear as old ones fade. This condition differs from other forms of urticaria (hives) — see Hives for the general allergic urticaria entry. The nettle plant injects a mix of irritants including histamine, formic acid, and other compounds into the skin.
Common signs
- Small, pale, raised swellings (wheals) on skin with severe itching and burning.
- Red, inflamed areas, sometimes with white centers.
- Each lesion lasts a few hours.
- Successive crops of new welts may appear.
