Aquagenic urticaria, also known as "water allergy" and "water urticaria", is a rarely diagnosed form of physical urticaria. The defining symptom is a painful skin reaction resulting from contact with water. It is sometimes described as an allergy, although it is not a true histamine-releasing allergic reaction like other forms of urticaria. This seems to not be affected by different temperatures of water, such as cold or hot, or chemicals such as fluorine and chlorine, since it is reproduced with distilled water and medical saline.
