Allergic reaction?

Beebee

Went for a walk with my Lo, there was a mild wind in the air. Once inside the park all of a sudden she get red patches on one side of her face from her eye up to the forehead and tip of the nose.

I panicked so went straight back in the car, the redness disappeared.

Has one ever had that experience? Was this an allergy or could be from a congested nose on a windy afternoon?
