Groups of large, itchyblisters usually then appear on the red patches, just beneaththe surface of the skin. They can be up to 5cm in diameter and full of fluid, with the thick skin of the blisters stretched tightly.

The fluidinside is usually clear, but can turn cloudy or bloodstained.

Blisters last a few days before healing without leaving a scar, but a cycle developswhere more form.
