What causes physical urticaria?
ANSWER
Physical urticaria refers to hives caused by direct physical stimulation of the skin -- for example, cold, heat, sunlight, vibration, pressure, sweating, and exercise. They usually happen right where the skin was affected and rarely appear anywhere else. Most appear within 1 hour after exposure.
